Spring整合SpringMVC框架
springmvc.xml配置注解扫描
- 细节
<!--开启注解扫描,只扫描Controller注解-->
<context:component-scan base-package="com.wl">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<a href="account/findAll">测试</a>
package com.wl.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* 账户web
*/
@Controller
@RequestMapping("/account")
public class AccountController {
@RequestMapping("/findAll")
public String finaAll() {
System.out.println("表现层,查询所有的账户信息...");
return "list";
}
}
运行结果
开始整合
配置监听器
<!--配置Spring的监听器 默认只加载WEB-INF目录下的applicationContext.xml配置文件-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--设置配置文件的路径-->
<!--但是由于SpringConfig.xml配置文件不在WEB-INF目录下,所以需要指定路径-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
package com.wl.controller;
import com.wl.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* 账户web
*/
@Controller
@RequestMapping("/account")
public class AccountController {
@Autowired
private AccountService accountService;
@RequestMapping("/findAll")
public String finaAll() {
System.out.println("表现层,查询所有的账户信息...");
//调用service的方法
accountService.findAll();
return "list";
}
}
运行结果
