netty和spring的结合  
上篇将netty大致部署好了，但是里面的配置我们都是写在代码里面，其实这样是不太好的，毕竟你改个参数就要打包一下。  
所以打算写在配置文件中，顺便把spring也集成进来

第一步，在pom文件中加入spring的包,

<spring.version>4.2.4.RELEASE</spring.version>这个写在properties标签里面，

其他写在dependencys标签里面

<spring.version>4.2.4.RELEASE</spring.version>

<dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>$\{spring.version\}</version> </dependency> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-redis</artifactId> <version>1.6.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-commons</artifactId> <version>1.11.2.RELEASE</version> </dependency>第二步，添加配置文件server-config-dev.properties，用这种写法就可以了

#
    code.debug=true
    port=8088
    channelType=NIO
    protocolType=TCP

第三步，添加spring的配置文件ApplicationContext.xml，里面的各个标签都有加注解，应该挺容易阅读的

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:context="http://www.springframework.org/schema/context"
           xmlns:tx="http://www.springframework.org/schema/tx"
           xmlns:task="http://www.springframework.org/schema/task"
           xsi:schemaLocation="http://www.springframework.org/schema/beans
    						http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
    						http://www.springframework.org/schema/context
    						http://www.springframework.org/schema/context/spring-context-4.2.xsd
    						http://www.springframework.org/schema/tx 
    						http://www.springframework.org/schema/tx/spring-tx-4.2.xsd
    						http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.2.xsd">
    
      
      <context:annotation-config/>
    
      
      <context:component-scan base-package="com.lizhaoblog">
      </context:component-scan>
    
      
      
      
      
    
      
      <bean id="cfgProps" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="locations">
          <list>
            <value>classpath:properties/server-config-dev.properties</value>
          </list>
        </property>
      </bean>
      <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="properties" ref="cfgProps">
        </property>
      </bean>
    
    
      <bean id="log4jInitializer" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
        <property name="targetClass"
                  value="org.springframework.util.Log4jConfigurer"/>
        <property name="targetMethod" value="initLogging"/>
        <property name="arguments">
          <list>
            <value>classpath:log4j-dev.xml</value>
          </list>
        </property>
      </bean>
    </beans>

第四步，修改ServerConfig类中的代码，里面的变量可以直接指向cfgProps中设置的值，如

@Value("\#\{cfgProps\['port'\]\}")

private Integer port;

设置初始化方法init，通过PostConstruct注解，初始化之后执行。

    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Value;

    import javax.annotation.PostConstruct;
    
    /**

     */
    @Component
    @Scope("singleton")
    public class ServerConfig {
      private static final Logger logger = LoggerFactory.getLogger(ServerConfig.class);
    
      @Value("#{cfgProps['port']}")
      private Integer port;
      @Value("#{cfgProps['channelType']}")
      private String channelType;
      @Value("#{cfgProps['protocolType']}")
      private String protocolType;
    
      private ApplicationContext applicationContext;
    
      private static ServerConfig instance = null;
    
      private ServerConfig() {
      }
    
      public static ServerConfig getInstance() {
        if (instance == null) {
          instance = new ServerConfig();
          logger.debug("ServerConfig is not init by spring");
        }
        return instance;
      }
    
      @PostConstruct
      public void init() {
        instance = this;
        printServerInfo();
      }
    
      public void printServerInfo() {
        logger.info("**************Server INFO******************");
        logger.info("protocolType  : " + protocolType);
        logger.info("port          : " + port);
        logger.info("channelType   : " + channelType);
        logger.info("**************Server INFO******************");
      }
    
      public Integer getPort() {
        return port;
      }
    
      public void setPort(Integer port) {
        this.port = port;
      }
    
      public String getChannelType() {
        return channelType;
      }
    
      public void setChannelType(String channelType) {
        this.channelType = channelType;
      }
    
      public String getProtocolType() {
        return protocolType;
      }
    
      public void setProtocolType(String protocolType) {
        this.protocolType = protocolType;
      }
    
      public ApplicationContext getApplicationContext() {
        return applicationContext;
      }
    
      public void setApplicationContext(ApplicationContext applicationContext) {
        this.applicationContext = applicationContext;
      }
    }

这样spring就整合完成了，可以在各个地方使用 applicationContext.getBean("xxx")获取某些类了  
而applicationContext对象我在ServerConfig之中保存了，需要  
ServerConfig.getInstance().getApplicationContext().getBean("xxx");
