SSM集成

单独集成Spring

1.创建javaweb项目
2.导入springjar
3.准备配置文件applicationContext.xml,并且配置对象
4.测试
能从spring中或bean就ok

public class SpringTest extends BaseTest
{

    @Autowired
    private Date myDate;
    @Test
    public void test()throws Exception{

        System.out.println(myDate);
    }
}

Spring+SpringMVC

导入jar
配置web.xml
字符编码过滤器
方案1:子从上下文

<?xml version="1.0" encoding="UTF-8"?>

<!--方案1:独立容器方案,spring和springmvc都有自己context-->
<!--1.1 spring容器初始化-->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
</context-param>

<!--1.2 配置springmvc-->
<servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <!--/*会拦截所有包括jsp-->
    <!--/会拦截所有但是不包含jsp-->
    <url-pattern>/</url-pattern>
</servlet-mapping>

<!--
    post请求乱码解决
   get请求实在tomcat猫中配置
-->
<filter>
    <filter-name>EncodingFilter</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>EncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<!--方案2:只有儿子容器-->
<servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <!--/*会拦截所有包括jsp-->
    <!--/会拦截所有但是不包含jsp-->
    <url-pattern>/</url-pattern>
</servlet-mapping>

applicationContext-mvc.xml

默认控制器
视图解析器
文件上传

<?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:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!--扫描controller-->
    <context:component-scan base-package="cn.itsource.ssm.controller" />
    <!--静态资源处理-->
    <mvc:default-servlet-handler />
    <!--识别@requestMapper等注解支持-->
    <mvc:annotation-driven />
    <!--配置视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

Spring集成到MyBatis

jdbc.properties—>Datasource ---->SqlSessionFactory----扫描Repository—>事务管理器-开启注解事务

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
	<!-- 注入数据源 -->
	<property name="dataSource" ref="dataSource" />
	<!-- 配置mybatis (mapper)映射器路径 -->
	<property name="mapperLocations" value="classpath:cn/itsource/ssm/mapper/*Mapper.xml" />
	<!-- 配置mybatis 类型别名 -->
	<property name="typeAliasesPackage">
		<value>
			cn.itsource.ssm.domain
			Cn.itsource.ssm.query  可能有查询对象
		</value>
	</property>
</bean>

一个一个配置

<bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
		<property name="sqlSessionFactory" ref="sqlSessionFactory" />
		<property name="mapperInterface" value="cn.itsource.ssm.mapper.UserMapper" />
	</bean>

一劳永逸
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="cn.itsource.ssm.mapper"></property>
	</bean>
