SSM基础框架的搭建和测试

﹏ヽ暗。殇╰゛Y 2022-06-10 09:13 204阅读 0赞

**一.配置server端的web.xml**

**配置监听器**

**<?xml version="1.0" encoding="UTF-8"?>  
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"  
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   
http://java.sun.com/xml/ns/javaee/web-app\_2\_5.xsd">  
  
<context-param>  
<param-name>contextConfigLocation</param-name>  
<param-value>classpath:application-context.xml</param-value>  
</context-param>  
  
<listener>  
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
</listener>  
</web-app>**

**二，配置application-context.xml**

**1.头文件**

**2.导入其他所有配置文件，或者将下面所有文件都合并到Application-context.xml 除jdbc.properties**

<import resource="config/\*.xml"/>

注：后面配至文件统一放到classpath即resource/config下

二.**数据库搭建(mysql&Druid)**

**1.数据源搭建**

**2.属性文件**

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
<property name="locations">  
<list>  
<value>classpath:jdbc.properties</value>  
</list>  
</property>  
</bean>

**3.mysql外部配置文件(**外部文件需名为jdbc.properties,且路径放在resource下，不可加目录**)**

driverClassName=com.mysql.jdbc.Driver  
url=jdbc:mysql://localhost:3306/babasport191?characterEncoding=UTF-8  
username=root  
password=root

**三.配置mybaits**

**1.导入数据库配置**

<bean class="org.mybatis.spring.SqlSessionFactoryBean">  
  
<property name="dataSource" ref="dataSource"/>  
  
<property name="configLocation" value="classpath:mybatis-config.xml"/>  
</bean>  
  
**2.mapper实现类的配置，采用MapperScannerConfigurer扫描dao；**

如何实现mapper有3种方式，可参阅上一遍博文  
  
  
  
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  
  
<property name="basePackage" value="cn.itcast.core.dao"/>

**3.配置mybits-config.xml**

别名的作用是方便在DAO.xml中不用输入类的全名

**<**?xml version="1.0" encoding="UTF-8" ?>  
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"  
"http://mybatis.org/dtd/mybatis-3-config.dtd">  
  
  
<configuration>

**四.配置控制端的web.xml**

<?xml version="1.0" encoding="UTF-8"?>  
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"  
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   
http://java.sun.com/xml/ns/javaee/web-app\_2\_5.xsd">  
  
  
<filter>  
<filter-name>encoding</filter-name>  
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
<init-param>  
<param-name>encoding</param-name>  
<param-value>UTF-8</param-value>  
</init-param>  
</filter>  
<filter-mapping>  
<filter-name>encoding</filter-name>  
<url-pattern>\*.do</url-pattern>  
</filter-mapping>  
  
<servlet>  
<servlet-name>console</servlet-name>  
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
<init-param>  
  
<param-name>contextConfigLocation</param-name>  
<param-value>classpath:springmvc-console.xml</param-value>  
</init-param>  
<load-on-startup>1</load-on-startup>  
</servlet>  
  
<servlet-mapping>  
  
<servlet-name>console</servlet-name>  
<url-pattern>\*.do</url-pattern>  
</servlet-mapping>  
  
</web-app>

**五.配置spring-mvc**

一个中心，前端控制器即DispatcherServlet  
三个基本点，处理器映射器 处理器适配器 视图解释器

**  
<context:component-scan base-package="cn.itcast" />  
  
<mvc:annotation-driven/>  
  
<bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
<property name="prefix" value="/WEB-INF/console/"/>  
<property name="suffix" value=".jsp"/>  
</bean>  
定义一个bean，可进行相关spring配置  
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>  
<import resource="dubbo-consumer.xml"/>**

**六 测试基础框架**

**1.测试dao和service**

**方法一**

**注junit需2.5以上，加载spring的application-context.xml，导入相关jar包**

@RunWith(SpringJUnit4ClassRunner.class)  
@ContextConfiguration(locations = \{"classpath:application-context.xml"\})  
public class TestTbTest \{  
@Autowired  
private TestTbService testTbService;  
@Test  
public void testAdd() throws Exception \{  
TestTb testTb = new TestTb();  
testTb.setName("范冰冰2");  
testTb.setBirthday(new Date());  
testTbService.insertTestTb(testTb);  
\}

**方法二，读取spring配置文件方式有改变**

**使用ApplicationContext读取applicationContext.xml文件，然后获取相应bean；**

public class SpringTest \{  
  
private ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");  
@Test  
public void testBean() throws Exception \{  
TestAction testAction = (TestAction) ac.getBean("testAction");  
System.out.println(testAction);  
\}  
// 测试SessionFactory  
@Test  
public void testSessionFactory() throws Exception \{  
SessionFactory sessionFactory = (SessionFactory) ac.getBean("sessionFactory");  
System.out.println(sessionFactory);  
\}  
// 测试事务  
@Test  
public void testTransaction() throws Exception \{  
TestService testService = (TestService) ac.getBean("testService");  
// testService.saveTwoUsers();  
testService.saveUsers25();  
\}

**七，测试Spring-MVC**

**输入UPL，看是否输入静态页面**

![Image 1][]@RequestMapping(value = "/index.do")  
public String toAdd(Model model)\{

return index;
