首先看下pom.xml配置的jar包：

application.properties里面配置数据库的链接信息

spring.mvc.view.prefix=/WEB-INF/jsp/
    
    spring.mvc.view.suffix=.jsp
    
    
    # Mysql 1
    mysql.datasource.test.url = jdbc:mysql://192.168.10.205:3306/test1
    mysql.datasource.test.username = root
    mysql.datasource.test.password = root
    
    mysql.datasource.test.minPoolSize = 3
    mysql.datasource.test.maxPoolSize = 25
    mysql.datasource.test.maxLifetime = 20000
    mysql.datasource.test.borrowConnectionTimeout = 30
    mysql.datasource.test.loginTimeout = 30
    mysql.datasource.test.maintenanceInterval = 60
    mysql.datasource.test.maxIdleTime = 60
    
    
    # Mysql 2
    mysql.datasource.test2.url =jdbc:mysql://192.168.10.205:3306/test2
    mysql.datasource.test2.username =root
    mysql.datasource.test2.password =root
    
    mysql.datasource.test2.minPoolSize = 3
    mysql.datasource.test2.maxPoolSize = 25
    mysql.datasource.test2.maxLifetime = 20000
    mysql.datasource.test2.borrowConnectionTimeout = 30
    mysql.datasource.test2.loginTimeout = 30
    mysql.datasource.test2.maintenanceInterval = 60
    mysql.datasource.test2.maxIdleTime = 60

DBConfig1，这个文件的作用设计把数据库的配置信息全部拿过来用 **atomikos**进行分布式管理：

package com.config;
    
    import org.springframework.boot.context.properties.ConfigurationProperties;
    /**
     * 
    *类描述：读取application.properties数据源1的配置信息，如用户名，密码等
    *@author: blank
    *@date： 日期：2018-1-24 时间：上午8:56:59
    *
     */
    @ConfigurationProperties(prefix = "mysql.datasource.test")
    public class DBConfig1 {
    
    	private String url;
    	private String username;
    	private String password;
    	private int minPoolSize;
    	private int maxPoolSize;
    	private int maxLifetime;
    	private int borrowConnectionTimeout;
    	private int loginTimeout;
    	private int maintenanceInterval;
    	private int maxIdleTime;
    	private String testQuery;
    	public String getUrl() {
    		return url;
    	}
    	public void setUrl(String url) {
    		this.url = url;
    	}
    	public String getUsername() {
    		return username;
    	}
    	public void setUsername(String username) {
    		this.username = username;
    	}
    	public String getPassword() {
    		return password;
    	}
    	public void setPassword(String password) {
    		this.password = password;
    	}
    	public int getMinPoolSize() {
    		return minPoolSize;
    	}
    	public void setMinPoolSize(int minPoolSize) {
    		this.minPoolSize = minPoolSize;
    	}
    	public int getMaxPoolSize() {
    		return maxPoolSize;
    	}
    	public void setMaxPoolSize(int maxPoolSize) {
    		this.maxPoolSize = maxPoolSize;
    	}
    	public int getMaxLifetime() {
    		return maxLifetime;
    	}
    	public void setMaxLifetime(int maxLifetime) {
    		this.maxLifetime = maxLifetime;
    	}
    	public int getBorrowConnectionTimeout() {
    		return borrowConnectionTimeout;
    	}
    	public void setBorrowConnectionTimeout(int borrowConnectionTimeout) {
    		this.borrowConnectionTimeout = borrowConnectionTimeout;
    	}
    	public int getLoginTimeout() {
    		return loginTimeout;
    	}
    	public void setLoginTimeout(int loginTimeout) {
    		this.loginTimeout = loginTimeout;
    	}
    	public int getMaintenanceInterval() {
    		return maintenanceInterval;
    	}
    	public void setMaintenanceInterval(int maintenanceInterval) {
    		this.maintenanceInterval = maintenanceInterval;
    	}
    	public int getMaxIdleTime() {
    		return maxIdleTime;
    	}
    	public void setMaxIdleTime(int maxIdleTime) {
    		this.maxIdleTime = maxIdleTime;
    	}
    	public String getTestQuery() {
    		return testQuery;
    	}
    	public void setTestQuery(String testQuery) {
    		this.testQuery = testQuery;
    	}
    	
    }

WebLogAspect：这里面是定义日志的内容：

package com.controller;
    
    import java.util.Enumeration;
    
    import javax.servlet.http.HttpServletRequest;
    import org.aspectj.lang.JoinPoint;
    import org.aspectj.lang.annotation.AfterReturning;
    import org.aspectj.lang.annotation.Aspect;
    import org.aspectj.lang.annotation.Before;
    import org.aspectj.lang.annotation.Pointcut;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.stereotype.Component;
    import org.springframework.web.context.request.RequestContextHolder;
    import org.springframework.web.context.request.ServletRequestAttributes;
    
    @Aspect//定义一个切面
    @Component
    public class WebLogAspect {
    	private Logger logger = LoggerFactory.getLogger(getClass());
    	@Pointcut("execution(public * com.controller..*.*(..))")//插入的地方
    	public void webLog() {
    	}
    	@Before("webLog()")
    	public void doBefore(JoinPoint joinPoint) throws Throwable {
    		// 接收到请求，记录请求内容
    		ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
    		HttpServletRequest request = attributes.getRequest();
    		// 记录下请求内容
    		logger.info("URL : " + request.getRequestURL().toString());
    		logger.info("HTTP_METHOD : " + request.getMethod());
    		logger.info("IP : " + request.getRemoteAddr());
    		Enumeration<String> enu = request.getParameterNames();
    		while (enu.hasMoreElements()) {
    			String name = (String) enu.nextElement();
    			logger.info("name:{},value:{}", name, request.getParameter(name));
    		}
    	}
    	@AfterReturning(returning = "ret", pointcut = "webLog()")
    	public void doAfterReturning(Object ret) throws Throwable {
    		// 处理完请求，返回内容
    		logger.info("RESPONSE : " + ret);
    	}
    
    }

IndexController：主类中里面应注解对各个方法进行调用：

package com.controller;
    
    import org.apache.log4j.Logger;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.cache.CacheManager;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    import org.springframework.web.bind.annotation.RestController;
    
    import com.test01.mapper.UserMapper01;
    import com.test02.mapper.UserMapper02;
    
    @RestController
    public class IndexController {
    
    	//使用日志
    	private static Logger log=Logger.getLogger(IndexController.class);
    	
    	@Autowired
    	private CacheManager cacheManager;
    	
    	//自定义数值
    //	@Value("${name}")
    //	private String name;
    
    	
    	@Autowired
    	private UserMapper01 userMapper1;
    
    	@Autowired
    	private UserMapper02 userMapper2;
    
    	@RequestMapping("/adduser")
    	public String adduser(String name, Integer age) {
    		userMapper1.insertUsers("大肠", 22);
    		userMapper2.insertUsers("阿干", 33);
    		return "success";
    	}
    	//写日志
    	@RequestMapping("/log")
    	public String log(){
    		log.info("test log");
    		return "success";
    	}
    	@ResponseBody
    	@RequestMapping("/addUserName")
    	public String addUserName(String name){
    		return "success";
    	}
    	//查询语句
    	@ResponseBody
    	@RequestMapping("/selectusers")
    	public String getUsers(Integer id){
    		return userMapper1.findUsersByid(id).toString();
    		
    	}
    	//清除缓存
    	@ResponseBody
    	@RequestMapping("/remoKey")
    	public String remoKey() {
    		cacheManager.getCache("baseCache").clear();
    		return "success";
    	}
    	//自定义数值
    //	@ResponseBody
    //	@RequestMapping("/getValue")
    //	public String getValue() {
    //		return name;
    //	}
    
    }

TestMyBatisConfig1，配置数据源信息（把数据源信息交给Atomikos来处理）：

package com.datasources;
    
    import java.sql.SQLException;
    
    import javax.sql.DataSource;
    
    
    import org.apache.ibatis.session.SqlSessionFactory;
    import org.mybatis.spring.SqlSessionFactoryBean;
    import org.mybatis.spring.SqlSessionTemplate;
    import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.beans.factory.annotation.Qualifier;
    import org.springframework.boot.jta.atomikos.AtomikosDataSourceBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.context.annotation.Primary;
    
    import com.config.DBConfig1;
    import com.mysql.jdbc.jdbc2.optional.MysqlXADataSource;
    
    
    
    @Configuration
    //basePackages 最好分开配置 如果放在同一个文件夹可能会报错
    @MapperScan(basePackages = "com.test01", sqlSessionTemplateRef = "testSqlSessionTemplate")
    
    public class TestMyBatisConfig1 {
    	// 配置数据源
    		@Primary
    		@Bean(name = "testDataSource")
    		public DataSource testDataSource(DBConfig1 testConfig) throws SQLException {
    			MysqlXADataSource mysqlXaDataSource = new MysqlXADataSource();
    			mysqlXaDataSource.setUrl(testConfig.getUrl());
    			mysqlXaDataSource.setPinGlobalTxToPhysicalConnection(true);
    			mysqlXaDataSource.setPassword(testConfig.getPassword());
    			mysqlXaDataSource.setUser(testConfig.getUsername());
    			mysqlXaDataSource.setPinGlobalTxToPhysicalConnection(true);
    
    			AtomikosDataSourceBean xaDataSource = new AtomikosDataSourceBean();
    			xaDataSource.setXaDataSource(mysqlXaDataSource);
    			xaDataSource.setUniqueResourceName("testDataSource");
    
    			xaDataSource.setMinPoolSize(testConfig.getMinPoolSize());
    			xaDataSource.setMaxPoolSize(testConfig.getMaxPoolSize());
    			xaDataSource.setMaxLifetime(testConfig.getMaxLifetime());
    			xaDataSource.setBorrowConnectionTimeout(testConfig.getBorrowConnectionTimeout());
    			xaDataSource.setLoginTimeout(testConfig.getLoginTimeout());
    			xaDataSource.setMaintenanceInterval(testConfig.getMaintenanceInterval());
    			xaDataSource.setMaxIdleTime(testConfig.getMaxIdleTime());
    			xaDataSource.setTestQuery(testConfig.getTestQuery());
    			return xaDataSource;
    		}
    
    		@Bean(name = "testSqlSessionFactory")
    		public SqlSessionFactory testSqlSessionFactory(@Qualifier("testDataSource") DataSource dataSource)
    				throws Exception {
    			SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
    			bean.setDataSource(dataSource);
    			return bean.getObject();
    		}
    
    		@Bean(name = "testSqlSessionTemplate")
    		public SqlSessionTemplate testSqlSessionTemplate(
    				@Qualifier("testSqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
    			return new SqlSessionTemplate(sqlSessionFactory);
    		}
    	}

Users实体：

package com.model;
    
    public class Users {
    	private int id;
    	private String name;
    	private int age;
    	public int getId() {
    		return id;
    	}
    	public void setId(int id) {
    		this.id = id;
    	}
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public int getAge() {
    		return age;
    	}
    	public void setAge(int age) {
    		this.age = age;
    	}
    	@Override
    	public String toString() {
    		return "Users [id=" + id + ", name=" + name + ", age=" + age + "]";
    	}
    	
    }

UserMapper01，对数据库1进行操作

package com.test01.mapper;
    
    import org.apache.ibatis.annotations.Insert;
    import org.apache.ibatis.annotations.Param;
    import org.apache.ibatis.annotations.Select;
    import org.springframework.cache.annotation.CacheConfig;
    import org.springframework.cache.annotation.Cacheable;
    
    import com.model.Users;
    
    @CacheConfig(cacheNames = "baseCache")
    public interface UserMapper01 {
    	
    	@Select("select * from users where id=#{id}")
    	@Cacheable
    	Users findUsersByid(@Param("id")Integer id);
    	
    //	@Select("select * from users")
    //	@Cacheable
    //	Users selectallUsers();
    	
    	@Insert("insert into users values(null,#{name},#{age});")
    	int insertUsers(@Param("name")String name,@Param("age")Integer age);
    }

service层：

package com.test01.service;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    import org.springframework.transaction.annotation.Transactional;
    import com.test01.mapper.UserMapper01;
    
    @Service
    public class UserService01 {
    	
    	@Autowired
    	private UserMapper01 userMapper1;
    	
    	//事务回滚，如果这部分出错，将会回滚
    	@Transactional
    	public int addUser(String name,Integer age){
    		return userMapper1.insertUsers(name, age);
    	}
    }

log4j.properties这里是配置日志：

#log4j.rootLogger=CONSOLE,info,error,DEBUG
    log4j.rootLogger=info,error,CONSOLE,DEBUG
    log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender     
    log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout     
    log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n     
    log4j.logger.info=info
    log4j.appender.info=org.apache.log4j.DailyRollingFileAppender
    log4j.appender.info.layout=org.apache.log4j.PatternLayout     
    log4j.appender.info.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n  
    log4j.appender.info.datePattern='.'yyyy-MM-dd
    log4j.appender.info.Threshold = info   
    log4j.appender.info.append=true   
    #log4j.appender.info.File=/home/admin/pms-api-services/logs/info/api_services_info
    log4j.appender.info.File=/Users/dddd/Documents/testspace/pms-api-services/logs/info/api_services_info
    log4j.logger.error=error  
    log4j.appender.error=org.apache.log4j.DailyRollingFileAppender
    log4j.appender.error.layout=org.apache.log4j.PatternLayout     
    log4j.appender.error.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n  
    log4j.appender.error.datePattern='.'yyyy-MM-dd
    log4j.appender.error.Threshold = error   
    log4j.appender.error.append=true   
    #log4j.appender.error.File=/home/admin/pms-api-services/logs/error/api_services_error
    log4j.appender.error.File=/Users/dddd/Documents/testspace/pms-api-services/logs/error/api_services_error
    log4j.logger.DEBUG=DEBUG
    log4j.appender.DEBUG=org.apache.log4j.DailyRollingFileAppender
    log4j.appender.DEBUG.layout=org.apache.log4j.PatternLayout     
    log4j.appender.DEBUG.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n  
    log4j.appender.DEBUG.datePattern='.'yyyy-MM-dd
    log4j.appender.DEBUG.Threshold = DEBUG   
    log4j.appender.DEBUG.append=true   
    #log4j.appender.DEBUG.File=/home/admin/pms-api-services/logs/debug/api_services_debug
    log4j.appender.DEBUG.File=/Users/dddd/Documents/testspace/pms-api-services/logs/debug/api_services_debug

ehcache.xml：配置缓存

<?xml version="1.0" encoding="UTF-8"?>
    <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"
    	updateCheck="false">
    	<diskStore path="java.io.tmpdir/Tmp_EhCache" />
    
    	
    	<defaultCache maxElementsInMemory="5000" eternal="false"
    		timeToIdleSeconds="120" timeToLiveSeconds="120"
    		memoryStoreEvictionPolicy="LRU" overflowToDisk="false" />
    
    	<cache name="baseCache" maxElementsInMemory="10000"
    		maxElementsOnDisk="100000" />
    
    </ehcache>

最后来到主程序：

APP：

package com.controller;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.boot.context.properties.EnableConfigurationProperties;
    import org.springframework.cache.annotation.EnableCaching;
    import org.springframework.context.annotation.ComponentScan;
    
    import com.config.DBConfig1;
    import com.config.DBConfig2;
    
    //有多个项目的时候，要加入这个注解，用来扫描包,扫描service层和dao层
    @ComponentScan(basePackages={"com.controller","com.config","com.datasources","com.test01","com.test02"})
    //开启缓存注解
    @EnableCaching
    //开启定时任务注解
    //@EnableScheduling
    //只能使用者一个注解
    @EnableAutoConfiguration
    //开启读取这两个配置文件
    @EnableConfigurationProperties(value = { DBConfig1.class, DBConfig2.class })
    public class App {
    	public static void main(String[] args) {
    		SpringApplication.run(App.class,args);
    	}
    
    }

最后启动。
