SSM(SpringMVC Spring Mybatis)框架整合搭建

1、新建一个web工程。

2、首先看一下整体的框架结构：

3、将ssm框架搭建所需要的jar包复制到lib目录下

3、需要配置各个配置文件。

1）配置web.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<web-app
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance
http://www.springmodules.org/schema/cache/springmodules-cache.xsd
http://www.springmodules.org/schema/cache/springmodules-encache.xsd"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<display-name>qzone</display-name>
<welcome-file-list>
<welcome-file>user.jsp</welcome-file>
</welcome-file-list>
<!-- spring配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext.xml</param-value>
</context-param>
<!-- spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- 编码过滤器 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<async-supported>true</async-supported>
<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>

<!-- 添加springmvc的支持 -->
<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:spring/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>

2）在resource/spring下创建applicationContext.xml配置文件：

    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd">
    <!-- 指定注解要扫描的包 -->
    <context:component-scan base-package="com.ekingwin.bas.cloud.user.web"></context:component-scan>
    <!-- 视图解析器，自动加上前缀和后缀 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"></property>
        <property name="suffix" value=".jsp"></property>

        select * from user where username=#{username}
    </select> -->
   <select id="getInfo" parameterType="String" resultType="map">
        select * from user where username=#{username}
    </select> 
</mapper>

8）在user/web下的到下创建UserController.java文件：

////        String username=user.getParameter("username");
////        List<Map<String,Object>> list =userDao.getInfo(username);
////        System.out.println(list.get(0).get("username"));
//        return null;
//    }
//    }

11）user/dto下创建UserDto.java文件：
