SSM(SpringMVC Spring Mybatis)框架整合搭建
阿新 • • 發佈:2018-11-11
1、新建一個web工程。
2、首先看一下整體的框架結構:
3、將ssm框架搭建所需要的jar包複製到lib目錄下
3、需要配置各個配置檔案。
1)配置web.xml檔案:
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance http://www.springmodules.org/schema/cache/springmodules-cache.xsd http://www.springmodules.org/schema/cache/springmodules-encache.xsd"xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>qzone</display-name> <welcome-file-list> <welcome-file>user.jsp</welcome-file> </welcome-file-list> <!-- spring配置檔案 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext.xml</param-value> </context-param> <!-- spring監聽器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 編碼過濾器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 新增springmvc的支援 --> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>
2)在resource/spring下建立applicationContext.xml配置檔案:

8)在user/web下的到下建立UserController.java檔案:
package com.ekingwin.bas.cloud.user.web; import javax.annotation.Resource; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; import com.ekingwin.bas.cloud.user.UserException; import com.ekingwin.bas.cloud.user.dao.entity.User; import com.ekingwin.bas.cloud.user.dto.UserDto; import com.ekingwin.bas.cloud.user.service.IUserService; import com.ekingwin.bas.cloud.user.service.impl.UserServiceImpl; //@RestController @Controller @RequestMapping("/user") public class UserController { @Autowired // @Qualifier(value = "userMetaServiceImpl") private IUserService userService; // // @Resource // private UserServiceImpl userService; // @RequestMapping(value = "/login", method = RequestMethod.POST) // public String login(UserDto user) throws UserException{ // System.out.println("123123"); // return userService.getmessage(user); // } @RequestMapping(value = "/login", method = RequestMethod.POST) public String login (@RequestBody UserDto user) throws UserException{ System.out.println("123123"); return userService.getmessage(user); // User resultUser = userService.login(user); // if(resultUser == null){ // request.setAttribute("user", user); // request.setAttribute("errorMsg","使用者名稱或密碼錯誤"); // return "index"; // }else{ // HttpSession session = request.getSession(); // session.setAttribute("currentUser",user); // return "redirect:/success.jsp"; // } // return null; } }
9)在user/service下建立IUserService.java:
