IDEA搭建SpringMVC并用maven配置的小例子（非常详细）

来源：互联网 发布：时间序列分析软件 编辑：程序博客网 时间：2024/05/20 10:53

想必作为Java开发来说，使用SpringMVC框架的应该是很熟悉，现在本人用IDEA搭建SpringMVC并用maven配置的一个小例子，记录下来，方便以后回头看看，写得不好的请指出，谢谢！

首先先准备好环境，本人使用的是jdk1.8.0_101，apache-tomcat-7.0.65，IntelliJIdea15，当然了无论使用版本不一样，但是都差不多的，可能不同的版本会有点不兼容，大家多试试就可以了。

1、用idea创建maven一个项目






此时已经创建好一个maven目录了

2、添加maven依赖


maven依赖代码如下，大致需要的包如下（表较全），根据不同的需求可以添加不同的依赖

3、添加表名com.springmvc下的dao,entity,controller,service,及service实现类并创建文件：

实体类：

package com.springmvc.entity;import java.io.Serializable;/** * Created by Vitelon on 2017-03-30 * 用户实体类. */public class User implements Serializable {private static final long serialVersionUID = 1L;/**用户ID*/private String id;/**用户名*/private String username;/**密码*/private String password;/**姓名*/private String sex;public User() {}public User(String id, String username, String password, String sex) {this.id = id;this.username = username;this.password = password;this.sex = sex;}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public String getSex() {return sex;}public void setSex(String name) {this.sex = sex;}@Overridepublic String toString() {return "User{" +"id='" + id + '\'' +", username='" + username + '\'' +", password='" + password + '\'' +", sex='" + sex + '\'' +'}';}}
dao接口：

package com.springmvc.dao;import com.springmvc.entity.User;import org.apache.ibatis.annotations.Param;import org.springframework.stereotype.Repository;import java.util.List;/** * Created by Vitelon on 2017-03-30 * 用户dao接口. */@Repository("UserDao")public interface UserDao {    /**     * Created by Vitelon on 2017-03-22     * 根据用户名和密码查询用户     * @param username     * @param password     * @return     */    public User findByUsernameAndPwd(@Param("username") String username, @Param("password") String password);    /**     * Created by Vitelon on 2017-03-30     * 获取用户     * @return     */    public List<User> find(User User);    /**     * Created by Vitelon on 2017-03-30     * 新增     * @param User     */    public void add(User User);    /**     * Created by Vitelon on 2017-03-30     * 修改     * @param User     */    public void update(User User);    /**     * Created by Vitelon on 2017-03-30     * 删除     * @param id     */    public void delete(String id);}
mapper配置文件：

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" ><mapper namespace="com.springmvc.dao.UserDao"><parameterMap id="parameterMap" type="com.springmvc.entity.User"></parameterMap><resultMap id="resultMap" type="com.springmvc.entity.User"><result property="id" column="id"/><result property="username" column="username"/><result property="password" column="password"/><result property="sex" column="sex"/></resultMap><sql id="columnSql"><trim suffixOverrides=",">t.id,t.username,t.password,t.sex, </trim></sql><select id="findByUsernameAndPwd" resultMap="resultMap">SELECT<include refid="columnSql"></include>FROM t_user tWHERE t.username = #{username} and t.password = #{password}</select></mapper>
service接口：

package com.springmvc.service;import com.springmvc.entity.User;import java.util.List;/** * Created by Vitelon on 2017-03-30 * 用户service接口 */public interface UserService {/** * Created by Vitelon on 2017-03-22 * 根据用户名和密码查询用户 * @param username * @param password * @return */public User findByUsernameAndPwd(String username, String password);/** * Created by Vitelon on 2017-03-30 * 获取用户 * @return */public List<User> find(User User);/** * Created by Vitelon on 2017-03-30 * 新增 * @param User */public void add(User User);/** * Created by Vitelon on 2017-03-30 * 修改 * @param User */public void update(User User);/** * Created by Vitelon on 2017-03-30 * 删除 * @param id */public void delete(String id);}

service实现类：

package com.springmvc.service.impl;import com.springmvc.dao.UserDao;import com.springmvc.entity.User;import com.springmvc.service.UserService;import org.springframework.stereotype.Service;import javax.annotation.Resource;import java.util.List;/** * Created by Vitelon on 2017-03-30 * 用户service实现类 */@Service("UserService")public class UserServiceImpl implements UserService {@Resource(name = "UserDao")private UserDao userDao;public User findByUsernameAndPwd(String name, String pwd) {return userDao.findByUsernameAndPwd(name, pwd);}public List<User> find(User user){return userDao.find(user);}public void add(User user) {userDao.add(user);}public void update(User user) {userDao.update(user);}public void delete(String id) {userDao.delete(id);}}

controller控制器：

package com.springmvc.controller;import com.springmvc.entity.User;import com.springmvc.service.UserService;import org.apache.commons.collections.map.HashedMap;import org.apache.log4j.Logger;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import java.util.Map;@Controller@RequestMapping("/user")public class ViewController {    private Logger logger = Logger.getLogger(ViewController.class);    @Resource(name = "UserService")    private UserService userService;    @RequestMapping("/index")    public String index(){        return "index";    }    @RequestMapping("/find")    @ResponseBody    public Map<String,Object> find(User user, HttpServletRequest request){        Map<String,Object> map = new HashedMap();        System.out.println("你已通过springMVC进入controller方法。。。。");        logger.info("你已通过springMVC进入controller方法。。。。");        User loginuser = userService.findByUsernameAndPwd(user.getUsername(),user.getPassword());        if(loginuser != null){            map.put("result","success");        }else {            map.put("result","fail");        }        return map;    }    @RequestMapping("/success")    public String success(){        System.out.println("登录成功。。。。");        logger.info("登录成功。。。。");        return "success";    }}

配置resources文件：

dbconfig.properties文件：

#MySQLjdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=truejdbc.username=rootjdbc.password=root#oracle#jdbc.driver=oracle.jdbc.driver.OracleDriver#jdbc.url=jdbc:oracle:thin:@localhost:3306:test#jdbc.username=root#jdbc.password=123456

数据库demo.sql文件：

/*Date: 2017-04-11 19:49:03*/SET FOREIGN_KEY_CHECKS=0;-- ------------------------------ Table structure for `t_user`-- ----------------------------DROP TABLE IF EXISTS `t_user`;CREATE TABLE `t_user` (  `id` varchar(11) NOT NULL,  `username` varchar(40) NOT NULL,  `password` varchar(40) NOT NULL,  `sex` varchar(4) NOT NULL,  PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=utf8;-- ------------------------------ Records of t_user-- ----------------------------INSERT INTO `t_user` VALUES ('1', 'user', '123', '男');

<?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:p="http://www.springframework.org/schema/p"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-4.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <description>Spring MVC Configuration</description><!-- 启用spring mvc 注解, 默认的注解映射的支持 --><mvc:annotation-driven/><!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 --><context:component-scan base-package="com.springmvc"/><bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver"><property name="defaultLocale" value="zh_CN" /></bean><mvc:interceptors><bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" /></mvc:interceptors><!-- 支持返回json(避免IE在ajax请求时，返回json出现下载文件 ) --><bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"><property name="supportedMediaTypes"><list><value>text/html;charset=UTF-8</value><value>text/json;charset=UTF-8</value><value>application/json;charset=UTF-8</value></list></property></bean><!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射， 配置一个基于注解的定制的WebBindingInitializer，解决日期转换问题，方法级别的处理器映射 --><bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"><property name="cacheSeconds" value="0" /><property name="messageConverters"><list><ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 --></list></property></bean><!-- 默认的视图解析器  --><bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:order="3"><property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/><property name="contentType" value="text/html" /><property name="prefix" value="/WEB-INF/page/"/><property name="suffix" value=".jsp"/><!--可为空,方便实现自已的依据扩展名来选择视图解释类的逻辑  --></bean><!-- 配置springMVC处理上传文件的信息 --><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><property name="defaultEncoding" value="utf-8" /><property name="maxUploadSize" value="10485760000" /><property name="maxInMemorySize" value="40960" /></bean><!-- Bean解析器,级别高于默认解析器,寻找bean对象进行二次处理 --><bean class="org.springframework.web.servlet.view.BeanNameViewResolver" p:order="0"/><!-- 对静态资源文件的访问， 将无法mapping到Controller的path交给default servlet handler处理 --><mvc:default-servlet-handler /><!-- 静态资源映射 --><mvc:resources mapping="/static/**" location="/static/" cache-period="31536000"/></beans>

4、配置tomcat






此时tomcat就配置好了。

5、接下来创建静态资源文件


6、配置web.xml文件


<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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>Manager</display-name><context-param><description>配置Spring配置文件路径</description><param-name>contextConfigLocation</param-name><!-- 如果是监听多个文件，可用‘，’隔开 --><param-value>classpath:spring-*.xml</param-value></context-param><listener><description>配置Spring上下文监听器</description><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><listener><description>Introspector缓存清除监听器</description><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener><listener><description>request监听器</description><listener-class>org.springframework.web.context.request.RequestContextListener</listener-class></listener><!-- 配置Spring字符编码过滤器 --><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><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!--log4j配置文件加载--><context-param><param-name>log4jConfigLocation</param-name><param-value>classpath:log4j.properties</param-value></context-param><!--启动一个watchdog线程每1800秒扫描一下log4j配置文件的变化--><context-param><param-name>log4jRefreshInterval</param-name><param-value>1800000</param-value></context-param><!--spring log4j监听器--><listener><listener-class>org.springframework.web.util.Log4jConfigListener</listener-class></listener><!-- Spring MVC 核心控制器 DispatcherServlet 配置开始 --><servlet><servlet-name>SpringMVC</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 可以通过contextConfigLocation来自定义SpringMVC配置文件的位置，如不指定，则默认在WEB-INF目录下，名称为[<servlet-name>]-servlet.xml， 此时文件名必须为[<servlet-name>]-servlet.xml，否则会出错--><!--以下init-param是自定义SpringMVC的配置文件的位置 --><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><!-- 拦截设置 --><servlet-mapping><servlet-name>SpringMVC</servlet-name><!-- 此处可以可以配置成*.do，对应struts的后缀习惯 --><url-pattern>/</url-pattern></servlet-mapping><!-- Spring MVC 核心配置结束 --><!-- 激活Tomcat的defaultServlet来处理静态文件 --><servlet-mapping><servlet-name>default</servlet-name><url-pattern>/static/*</url-pattern></servlet-mapping><!-- session 时间 --><session-config><session-timeout>30</session-timeout></session-config></web-app>

7、在WEB-INF下创建文件夹page，主要放jsp文件




8、index文件


<%@ page contentType="text/html;charset=UTF-8" language="java" %><html>  <head>    <title>IDEA搭建SpringMVC并用maven配置的小例子</title>  </head>  <%--<link rel="stylesheet" href="/asset/css/style.css"/>--%>  <script type="text/javascript" src="/plugs/js/jquery-1.7.2.js"></script>  <body>        <form id="userForm" action="/user/find" method="post">          用户名：<input type="text" name="username"><br>          密码：<input type="password" name="password">          <button type="button" onclick="login()">登录</button>        </form>  </body><script>    function login() {        $.ajax({            type: 'post',            url: $('#userForm').attr('action'),            data: $('#userForm').serialize(),            dataType: 'json',            success: function(data){                if (data.result = "success"){                    alert("登录成功");                    location.href='/user/success';                }else{                    alert("用户名或者密码错误！");                }            }        });    }</script></html>

项目结构大致如下：





然后运行tomcat成功之后，在浏览器输入http://localhost:8080/user/index有如下结果：




输入用户名user和密码123就会跳转至登录成功的页面：






说明一个简单的SSM框架整合开发的例子就算搭建好了。

此步骤在本人的电脑下可以运行正常，可能大家在试的时候会有报错，有什么问题的大家可以多多百度找解决方案哦。
