8 Spring和SpringMVC整合

8.1 定义Controller

package com.wpj.web.controller;

import org.springframework.stereotype.*;

/**
 * ClassName: Controller
 * Description:
 *
 * @author JieKaMi
 * @version 1.0
 * @date: 2020\1\8 0008 21:55
 * @since JDK 1.8
 */
@Controller
@RequestMapping("/emp")
public class EmpController {
    
}

8.2 创建springmvc.xml并配置

<?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">

    <!-- 开启包扫描-->
    <context:component-scan base-package="com.wpj" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- 开启注解驱动-->
    <mvc:annotation-driven/>
    <!-- 配置thymeleaf的视图解析器-->
    <bean id="templateResolver"
          class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver"> <!--前缀配置-->
        <property name="prefix" value="/"></property> <!--后缀配置-->
        <property name="suffix" value=".html"></property> <!--模板类型-->
        <property name="templateMode" value="HTML"></property> <!--不使用缓存-->
        <property name="cacheable" value="false"></property> <!--编码类型-->
        <property name="characterEncoding" value="UTF-8"></property>
    </bean>

    <!--模板引擎配置-->
    <bean id="templateEngine" class="org.thymeleaf.spring5.SpringTemplateEngine">
        <property name="templateResolver" ref="templateResolver"></property>
    </bean>
    <!--视图处理器-->
    <bean class="org.thymeleaf.spring5.view.ThymeleafViewResolver">
        <property name="templateEngine" ref="templateEngine"></property>
        <property name="characterEncoding" value="UTF-8"></property>
    </bean>

    <!-- 静态资源文件处理-->
    <mvc:default-servlet-handler/>

</beans>

8.3 配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">
  <display-name>Archetype Created Web Application</display-name>

<!-- Filter-->
  <filter>
    <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!-- lsiteneter-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring-context.xml</param-value>
  </context-param>

  <!-- 在Tomcat启动的时候初始化Spring容器-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- Servlet-->
  <servlet>
    <servlet-name>DispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <!-- 优先级-->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

8.4 Controller写映射路径

package com.wpj.web.controller;

import com.wpj.bean.*;
import com.wpj.service.*;
import org.springframework.beans.factory.annotation.*;
import org.springframework.stereotype.*;
import org.springframework.ui.*;
import org.springframework.web.bind.annotation.*;

import java.util.*;

/**
 * ClassName: Controller
 * Description:
 *
 * @author JieKaMi
 * @version 1.0
 * @date: 2020\1\8 0008 21:55
 * @since JDK 1.8
 */
@Controller
@RequestMapping("/emp")
public class EmpController {

    @Autowired
    private IEmpService iEmpService;
    
    @RequestMapping("/getAllEmp")
    public String getAllEmp(ModelMap map){
        List<Emp> empList = iEmpService.getAllEmp();
        map.put("empList",empList);
        return "list";
    }
}

8.5 运行

http://localhost:8080/emp/getAllEmp
	emp ⇒   controller映射路径
	getAllEmp ⇒  controller内定义方法映射路径

8.6 结果

8.6.1 ssm整合成功。
