- 通过注解,将Service的生命周期纳入Spring的管理
- 配置数据源
- 注解事务
- 开启注解

springmvc.xml
- 配置Controller扫描
- 配置注解驱动
- 视图解释器
- 静态页面,如html,css,js,images可以访问

web.xml
- spring的配置文件
- 处理POST提交乱码问题
- 配置SpringMVC前端控制器
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" version="3.1"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- Spring监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 处理POST提交乱码问题 --> <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>/</url-pattern> </filter-mapping> <!-- 配置SpringMVC前端控制器 --> <servlet> <servlet-name>SSM</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 指定SpringMVC配置文件 --> <!-- SpringMVC的配置文件的默认路径是/WEB-INF/${servlet-name}-servlet.xml --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>SSM</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
- 至此框架就算搭建完成了,然后就是测试环节
新建一个student表
SET FOREIGN_KEY_CHECKS=0; -- ---------------------------- -- Table structure for `student` -- ---------------------------- DROP TABLE IF EXISTS `student`; CREATE TABLE `student` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(20) DEFAULT NULL, `age` int(11) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8; -- ---------------------------- -- Records of student -- ---------------------------- INSERT INTO `student` VALUES (‘1‘, ‘张三‘, ‘18‘); INSERT INTO `student` VALUES (‘2‘, ‘李四‘, ‘15‘); INSERT INTO `student` VALUES (‘3‘, ‘王五‘, ‘20‘); INSERT INTO `student` VALUES (‘4‘, ‘赵六‘, ‘22‘); INSERT INTO `student` VALUES (‘5‘, ‘孙琪‘, ‘24‘); INSERT INTO `student` VALUES (‘6‘, ‘路飞‘, ‘19‘);
创建student pojo对象
package com.ssm.pojo; import java.io.Serializable; /** * Created by ${DX} on 2018/9/28. */ public class Student { private int id; private String name; private int age; public Student(int id, String name, int age) { this.id = id; this.name = name; this.age = age; } @Override public String toString() { return "Student{" + "id=" + id + ", name=‘" + name + ‘\‘‘ + ", age=" + age + ‘}‘; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }
StudentDao
package com.ssm.dao; import com.ssm.pojo.Student; import org.springframework.stereotype.Repository; import java.util.List; /** * Created by ${DX} on 2018/9/28. */ @Repository public interface StudentDao { List<Student> findAllStudent(); }
StudentDao.xml
<?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.ssm.dao.StudentDao"> <select id="findAllStudent" resultType="Student"> SELECT * FROM student; </select> </mapper>
测试方法StudentDaoTest
package test; import com.ssm.dao.StudentDao; import com.ssm.pojo.Student; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import java.util.List; /** * Created by ${DX} on 2018/9/28. */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:applicationContext.xml") public class StudentDaoTest { @Autowired private StudentDao studentDao; @Test public void test(){ List<Student> students=studentDao.findAllStudent(); System.out.println(students.size()); } }
测试通过
接下来是service层
StudentService
package com.ssm.service; import com.ssm.pojo.Student; import java.util.List; /** * Created by ${DX} on 2018/9/29. */ public interface StudentService { List<Student> findAllStudent(); }
StudentServiceImpl
package com.ssm.service; import com.ssm.dao.StudentDao; import com.ssm.pojo.Student; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; /** * Created by ${DX} on 2018/9/29. */ @Service public class StudentServiceImpl implements StudentService { @Autowired private StudentDao studentDao; @Override public List<Student> findAllStudent() { return studentDao.findAllStudent(); } }
StudentSeviceTest
package test; import com.ssm.pojo.Student; import com.ssm.service.StudentService; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import java.util.List; /** * Created by ${DX} on 2018/9/29. */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:applicationContext.xml") public class StudentSeviceTest { @Autowired private StudentService studentService; @Test public void test(){ List<Student> students=studentService.findAllStudent(); System.out.println(students.size()); } }
service层测试通过
最后就是controller层
StudentController
package com.ssm.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; /** * Created by ${DX} on 2018/9/29. */ @Controller @RequestMapping("/student") public class StudentController { @RequestMapping("/index") public String index(){ return "hello"; } }
hello.jsp
<%-- Created by IntelliJ IDEA. User: Administrator Date: 2018/9/29 Time: 0:11 To change this template use File | Settings | File Templates. --%> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Title</title> </head> <body> HELLO SSM!!!! </body> </html>
开启服务器后,页面访问/student/index 就会跳转到hello.jsp 页面
至此 ssm 框架搭建测试完毕!!!
