今天完成的事情

1，首先是完成没有CRUD功能的SSM整合。

接着昨天的进度，首先是applicationContext.xml的配置

 <context:annotation-config />
    <context:component-scan base-package="com.sx.service" />

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName">
            <value>com.mysql.jdbc.Driver</value>
        </property>
        <property name="url">
            <value>jdbc:mysql://localhost:3306/school</value>

        </property>
        <property name="username">
            <value>root</value>
        </property>
        <property name="password">
            <value>shenxuan52142</value>
        </property>
    </bean>

    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="typeAliasesPackage" value="com.sx.pojo" />
        <property name="dataSource" ref="dataSource"/>
        <property name="mapperLocations" value="classpath:com/sx/mapper/*.xml"/>
    </bean>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.sx.mapper"/>
    </bean>

</beans>

然后是spring-mvc.xml的配置

    <context:annotation-config/>

    <context:component-scan base-package="com.sx.controller">
        <context:include-filter type="annotation"
                                expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <mvc:annotation-driven />

    <mvc:default-servlet-handler />

    <!-- 视图定位 -->
    <bean
            class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass"
                  value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

以及web.xml的配置

 <!-- spring的配置文件-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- spring mvc核心：分发servlet -->
  <servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- spring mvc的配置文件 -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

listStudentS.jsp的配置

<%@ page language="java" contentType="text/html; charset=UTF-8"
         pageEncoding="UTF-8" import="java.util.*"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<table align='center' border='1' cellspacing='0'>
    <tr>
        <td>id</td>
        <td>name</td>
        <td>age</td>
    </tr>
    <c:forEach items="${cs}" var="c" varStatus="st">
        <tr>
            <td>${c.id}</td>
            <td>${c.name}</td>
            <td>${c.age}</td>

        </tr>
    </c:forEach>
</table>

然后是StudentSController

@Controller
@RequestMapping({""})
public class StudentSController {
    @Autowired
    StudentSService studentSService;
    public StudentSController(){}
    @RequestMapping({"listStudentS"})
    public ModelAndView listStudentS(){
        ModelAndView mav = new ModelAndView();
        List<StudentS> cs=studentSService.list();

        // 放入转发参数
        mav.addObject("cs", cs);
        // 放入jsp路径
        mav.setViewName("listStudentS");
        return mav;
    }

最后配置TOMCAT，运行

2.开始进行CRUD的SSM整合

首先在service中添加

public class StudentSServiceImpl implements StudentSService {
    @Autowired
    StudentSMapper studentSMapper;
    public StudentSServiceImpl(){}

    public List<StudentS> list() {
        return studentSMapper.list();
    }

    public void add(StudentS c) {
        studentSMapper.add(c);
    }

    public void delete(StudentS c) {
        studentSMapper.delete(c.getId());
    }

    public void update(StudentS c) {
        studentSMapper.update(c);
    }

    public StudentS get(int id) {
        return studentSMapper.get(id);
    }
}

然后在listStudentS中添加

<%@ page language="java" contentType="text/html; charset=UTF-8"
         pageEncoding="UTF-8" import="java.util.*"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<div style="width:500px;margin:0px auto;text-align:center">
<table align='center' border='1' cellspacing='0'>
    <tr>
        <td>id</td>
        <td>name</td>
        <td>age</td>
        <td>编辑</td>
        <td>删除</td>
    </tr>
    <c:forEach items="${cs}" var="c" varStatus="st">
        <tr>
            <td>${c.id}</td>
            <td>${c.name}</td>
            <td>${c.age}</td>
            <td><a href="editStudentS?id=${c.id}">编辑</a></td>
            <td><a href="deleteStudentS?id=${c.id}">删除</a></td>

        </tr>
    </c:forEach>
</table>
    <div style="text-align:center;margin-top:40px">

        <form method="post" action="addStudentS">
            分类名称： <input name="name" value="" type="text"> <br><br>
            <input name="age" value="${c.age}" type="text">
            <input name="id" value="${c.id}" type="text" >
            <input type="submit" value="增加分类">
        </form>

    </div>


</div>

然后在控制器中添加


@Controller
@RequestMapping({""})
public class StudentSController {
    @Autowired
    StudentSService studentSService;
    public StudentSController(){}
    @RequestMapping({"listStudentS"})
    public ModelAndView listStudentS(){
        ModelAndView mav = new ModelAndView();
        List<StudentS> cs=studentSService.list();

        // 放入转发参数
        mav.addObject("cs", cs);
        // 放入jsp路径
        mav.setViewName("listStudentS");
        return mav;
    }
    @RequestMapping("addStudentS")
    public ModelAndView addStudentS(StudentS studentS){
        studentSService.add(studentS);
        ModelAndView mav=new ModelAndView("redirect:/listStudentS");
        return mav;
    }
    @RequestMapping("deleteStudentS")
    public ModelAndView deleteStudentS(StudentS studentS){
        studentSService.delete(studentS);
        ModelAndView mav = new ModelAndView("redirect:/listStudentS");
        return mav;
    }
    @RequestMapping("updateStudentS")
    public ModelAndView updateStudentS(StudentS studentS){
        studentSService.update(studentS);
        ModelAndView mav = new ModelAndView("redirect:/listStudentS");
        return mav;
    }
    @RequestMapping("editStudentS")
    public ModelAndView editStudentS(StudentS studentS){
        StudentS c= studentSService.get(studentS.getId());
        ModelAndView mav = new ModelAndView("editStudentS");
        mav.addObject("c", c);
        return mav;
    }

}
