Intellij idea下使用Maven管理的Spring+SpringMVC+Mybatis的整合
来源：互联网 发布：鸳鸯是一夫一妻吗 知乎 编辑：程序博客网 时间：2024/06/11 17:39
近日在研究java框架，在学习了Spring、SpringMVC、Mybatis三大框架之后，历经千辛万苦，终于将SSM框架整合成功，下面贴上我的过程
1 > 创建maven webapp项目
2 > java下创建ssm -
|-controller
|-dao
|-service
|-model
3 > web.xml配置
<?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_3_0.xsd" version="3.0"> <welcome-file-list> <welcome-file>/index.html</welcome-file> </welcome-file-list> <display-name>web-ssm</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.properties</param-value> </context-param> <!-- 编码过滤器 --> <filter> <filter-name>encodingFilter</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>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- spring监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止spring内存溢出监听器，比如quartz --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- spring mvc servlet--> <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-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> <!-- session配置 --> <session-config> <session-timeout>15</session-timeout> </session-config></web-app>
3 > 在webapp下创建一个index.html文件，实现一个ajax
<html><body><h2>Hello World!</h2></body><script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js"></script><script type="text/javascript"> $(document).ready(function () { $.ajax({ url: "/test.do", method: "POST", data: "aaaaa", success: function (data) { alert(data); } }); });</script></html>4 > pom.xml 导入需要的包

以下文件为放入/resources中
spring-mybatis.xml(spring的配置文件)

5 > java文件
dao、service之类的是spring、mybatis相关的，此处不再赘述
6 > BlogController.java 使用ajax方式的配置
package ssm.controller;import org.apache.log4j.Logger;import org.junit.Test;import org.springframework.stereotype.Controller;import org.springframework.test.context.ContextConfiguration;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.ResponseBody;import ssm.model.Blog;import ssm.service.BlogService;import javax.annotation.Resource;import java.util.List;/** * Created by sidhch on 2017/4/8. *///@ContextConfiguration(locations = {"classpath:spring-mybatis.xml"})@Controllerpublic class BlogController { private Logger logger = Logger.getLogger(Logger.class); @Resource private BlogService blogService; @RequestMapping("/test.do") @ResponseBody public String Test(@RequestBody String str) { logger.info("查询博客信息"); List<Blog> blogList = blogService.getAllBlog(); for (Blog b : blogList) { logger.info("title ===== " + b.getTitle()); } return "success!===" + str; }}配置到此结束。
