IDEA搭建Spring+SpringMVC+mybatis框架教程

IDEA搭建Spring+SpringMVC+mybatis框架教程

IDEA版本：IDEA 2017.2.5
JDK版本：JDK1.8
测试数据库表sql自取如下：

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for `user`
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` varchar(10) NOT NULL,
  `name` varchar(20) default NULL,
  `sex` varchar(5) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO `user` VALUES ('1', '张三', '男');
INSERT INTO `user` VALUES ('2', '张三2', '女');
INSERT INTO `user` VALUES ('3', '张三3', '男');
INSERT INTO `user` VALUES ('4', '张三4', '男');
INSERT INTO `user` VALUES ('5', '张三5', '男');
INSERT INTO `user` VALUES ('6', '张三6', '男');
INSERT INTO `user` VALUES ('7', '张三7', '男');
INSERT INTO `user` VALUES ('8', '张三8', '男');

废话不多说，直入正题。
步骤
一：创建Maven webapp项目

把项目文件建起来，如图所示（注意，test目录和main平级），并对文件夹进行标识让IDEA系统系别。

二：配置文件内容
pom.xml文件

logback.xml（用log4j也行哦~），自行配置输出

jdbc.properties

jdbc.driverLocation=D:\\mavenRep\\repository\\mysql\\mysql-connector-java\\5.1.29\\mysql-connector-java-5.1.29.jar
jdbc.driverClasss=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/kaka?useUnicode=true&characterEncoding=UTF-8
#username直接声明会与系统jvm冲突，不信你试试~
jdbc.username=xxx
jdbc.password=xxx

开启mybatis逆向工程，生成dao（即mapper）和model（即po）
先写逆向工程配置文件generatorConfig.xml

<generatorConfiguration>
    
    <properties resource="jdbc.properties">properties>

    
    <classPathEntry location="${jdbc.driverLocation}"/>

    <context id="default" targetRuntime="MyBatis3">

        
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="true"/>
        commentGenerator>

        
        <jdbcConnection
                driverClass="${jdbc.driverClasss}"
                connectionURL="${jdbc.url}"
                userId="${jdbc.username}"
                password="${jdbc.password}">
        jdbcConnection>


        
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        javaTypeResolver>


        
        <javaModelGenerator targetPackage="com.kaka.model"
                            targetProject="src/main/java">

            
            <property name="enableSubPackages" value="false"/>
            
            <property name="constructorBased" value="true"/>
            
            <property name="trimStrings" value="true"/>
            
            <property name="immutable" value="false"/>
        javaModelGenerator>

        
        <sqlMapGenerator targetPackage="com.kaka.dao"
                         targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
        sqlMapGenerator>

Run/Debug Configuration注册maven运行项

点击右边的绿色箭头启动。
成功之后如下：

三：临时测试一下数据访问能否成功
创建如下目录中的UserMapperTest.java文件

测试成功（要是没成功，自己找找问题~）：

四：接下来可以进行web的开发咯~
首先，测试index.jsp
在webapp文件下创建index.jsp文件

<%--

<html>
<head>
    <title>测试标题title>
head>
<body>
欢迎大家访问！
body>
html>

然后点击右上角的Edit Configuration…然后点击“+”号

创建tomcat，并部署（如下图所示，记得给汤姆猫起个名字哦）

然后切换到server选项卡进行如下设置

来来来！！！启动了！！！
启动成功

看到了！成功访问了index.jsp，很激动！！！有木有！！！

最后，我们创建Controller和Service进行最后的冲刺！
UserService.java

package com.kaka.service;

import com.kaka.dao.UserMapper;
import com.kaka.model.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class UserService {

    @Autowired
    private UserMapper userMapper;

    public User getUserById(String id){
        return userMapper.selectByPrimaryKey(id);
    }
}

UserController.java

package com.kaka.controller;

import com.kaka.model.User;
import com.kaka.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("user")
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("getUser")
    public ModelAndView getUser(String id){
        ModelAndView modelAndView = new ModelAndView();
        User user = userService.getUserById(id);
        modelAndView.addObject("user",user);
        modelAndView.setViewName("user/getUser");
        return modelAndView;
    }
}

赶紧在WEB-INF下面的jsp文件夹下面创建如下文件

getUser.jsp

开始秋天的收获！！！
汤姆猫，该工作了！

Success!
bye~~
