SSM框架简单应用

这个是我的项目

jar包

maven项目pom.xml配置。。。根据maven导过来的，你们直接复制用就OK了

我这里面有一个是ojdbc6，是我从本地仓库得来的，你们这个要自己弄

<!-- 指定需要扫描的注解包路径，这里的（com.jingyan.**）是需要自己的包。扫描所有com.jingyan下面的注解包 -->

<!-- 以上是SpringMVC的配置 -->

</beans>

web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"

<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>


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


<!-- 监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>


<!-- 引入SpringMVC -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>

</init-param>
</servlet>
<servlet-mapping>

<filter>

</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>

然后配置文件就搞定了

之后就是entity层，也就是封装类

package com.jingyan.entity;


public class Student {
private Integer stid;
private String stname;
@Override
public String toString() {
return "Student [stid=" + stid + ", stname=" + stname + "]";
}
public Integer getStid() {
return stid;
}
public void setStid(Integer stid) {
this.stid = stid;
}
public String getStname() {
return stname;
}
public void setStname(String stname) {
this.stname = stname;
}

}

然后是mapper.xml里面的sql语句

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.jingyan.mapper.StudentMapper">

        <!--这里就是上面applicationContext里面配置类别名，直接Student就好了 -->
<select id="selectAll" resultType="Student">
select * from student
</select>

</mapper>

再就是mapper接口层

package com.jingyan.mapper;


import java.util.List;


import org.springframework.stereotype.Repository;


import com.jingyan.entity.Student;


@Repository
public interface StudentMapper {

public List<Student> selectAll();

}

service层

package com.jingyan.services;


import java.util.List;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


import com.jingyan.entity.Student;
import com.jingyan.mapper.StudentMapper;


@Service
public class StudentServices {

@Autowired
private StudentMapper studentmapper;

public List<Student> selectAll(){
return studentmapper.selectAll();
}

}

Controller层

package com.jingyan.controller;


import java.util.List;


import javax.servlet.http.HttpServletRequest;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;


import com.jingyan.entity.Student;
import com.jingyan.services.StudentServices;


@Controller
@RequestMapping("/studentcontroller")
public class StudnetController {

@Autowired
private StudentServices studentservices;

@RequestMapping("/selectAll")
public String selectAll(HttpServletRequest request){
List<Student> list = studentservices.selectAll();
request.setAttribute("list", list);
return "/index.jsp";
}

}

index.jsp  JSP页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html>

            <td>${student.stid}</td>
            <td>${student.stname}</td>
        </tr>
        </c:forEach>
