使用IDEA的gradle整合spring+ mybatis 采用javaconfig配置
1.新建一个工程
2.工程目录
3.添加gradle.propertes文件
activeMQVersion=5.7.0
aspectJVersion=1.7.2
commonsLangVersion = 3.1
ehcacheVersion=2.7.4
ehcacheJCacheVersion=1.4.0-beta1

hibernateValidatorVersion = 5.0.1.Final
jacksonVersion=2.4.3
javaxMailVersion=1.4.7
jspApiVersion = 2.1
jspElVersion = 2.2.4
jstlVersion = 1.2
junitVersion=4.12
log4jVersion=1.2.14
mockitoVersion=1.9.5
servletApiVersion = 3.1.0
slf4jVersion = 1.7.5
springAMQPVersion=1.0.0.RELEASE

tilesVersion = 3.0.1
mysql_Java = 5.1.38
commons_dbcp = 1.4
mybatis_spring =1.2.5
mybatisVersion = 3.3.1
4.添加依赖，修改build.gradle文件
group 'com.huang'
version '1.0-SNAPSHOT'
apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'eclipse'
apply plugin: 'idea'
sourceCompatibility = 1.5
repositories {
maven { url 'http://maven.springframework.org/release' }
maven { url 'http://maven.springframework.org/milestone' }
maven { url 'http://maven.springframework.org/snapshot' }
maven { url 'http://download.java.net/maven/2' }
mavenCentral()
}
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.12'
testCompile"org.springframework:spring-test:${springVersion}"
testCompile "com.github.stefanbirkner:system-rules:${systemRulesVersion}"
compile "org.springframework:spring-core:$springVersion"
compile "org.springframework:spring-context:$springVersion"
compile "org.springframework:spring-jdbc:$springVersion"
compile "org.mybatis:mybatis:$mybatisVersion"
compile "org.mybatis:mybatis-spring:$mybatis_spring"
compile "commons-dbcp:commons-dbcp:$commons_dbcp"
compile "mysql:mysql-connector-java:$mysql_Java"
compile "log4j:log4j:$log4jVersion"
compile "com.h2database:h2:$h2Version"
compile "javax.inject:javax.inject:1"
compile "net.sf.ehcache:ehcache:$ehcacheVersion"
compile "net.sf.ehcache:ehcache-jcache:$ehcacheJCacheVersion"
}
5.执行sql脚本，创建数据库表
SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for tbl_dep
-- ----------------------------
DROP TABLE IF EXISTS `tbl_dep`;
CREATE TABLE `tbl_dep` (
`depId` varchar(20) NOT NULL,
`name` varchar(20) DEFAULT NULL,
PRIMARY KEY (`depId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of tbl_dep
-- ----------------------------
INSERT INTO `tbl_dep` VALUES ('01', '总公司');
INSERT INTO `tbl_dep` VALUES ('0101', '一分公司');
INSERT INTO `tbl_dep` VALUES ('010101', '开发部');
INSERT INTO `tbl_dep` VALUES ('010102', '测试部');
INSERT INTO `tbl_dep` VALUES ('0102', '二分公司');
INSERT INTO `tbl_dep` VALUES ('010201', '开发部');
INSERT INTO `tbl_dep` VALUES ('010202', '测试部');
-- ----------------------------
-- Table structure for tbl_user
-- ----------------------------
DROP TABLE IF EXISTS `tbl_user`;
CREATE TABLE `tbl_user` (
`userId` varchar(20) NOT NULL,
`name` varchar(20) DEFAULT NULL,
`depId` varchar(20) NOT NULL,
`sex` varchar(10) DEFAULT NULL,
PRIMARY KEY (`userId`),
KEY `TBL_USER_FK` (`depId`),
CONSTRAINT `TBL_USER_FK` FOREIGN KEY (`depId`) REFERENCES `tbl_dep` (`depId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of tbl_user
-- ----------------------------
INSERT INTO `tbl_user` VALUES ('user0001', '张三1', '010101', '男');
INSERT INTO `tbl_user` VALUES ('user0002', '张三2', '010101', '男');
INSERT INTO `tbl_user` VALUES ('user0003', '张三3', '010102', '男');
INSERT INTO `tbl_user` VALUES ('user0004', '张三4', '010201', '男');
INSERT INTO `tbl_user` VALUES ('user0005', '张三5', '010201', '男');
INSERT INTO `tbl_user` VALUES ('user0006', '张三6', '010102', '男');
SET FOREIGN_KEY_CHECKS=1;
6.创建实体类User,对应tbl_user表
package com.huang.domain;
/**
* Created by huangyichun on 2016/12/9.
*/
public class User {
private String userId;
private String name;
private String depId;
private String sex;
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDepId() {
return depId;
}
public void setDepId(String depId) {
this.depId = depId;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
@Override
public String toString() {
return "User{" +
"userId='" + userId + '\'' +
", name='" + name + '\'' +
", depId='" + depId + '\'' +
", sex='" + sex + '\'' +
'}';
}
}
7. 创建接口UserMapper，其中部分采用注解形式
package com.huang.mapper;
import com.huang.domain.User;
import org.apache.ibatis.annotations.Delete;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import org.apache.ibatis.annotations.Update;
import java.util.List;
public interface UserMapper {
@Select("SELECT * FROM tbl_user")
List<User> getUserList();
@Select("SELECT * FROM tbl_user WHERE userId = #{userId}")
User getUserById(@Param("userId") String userId);
@Update("UPDATE tbl_user SET sex = #{sex} WHERE userId = #{userId}")
void updateUserEmailById(@Param("userId") String userId, @Param("sex") String sex);
@Delete("DELETE FROM tbl_user WHERE userId = #{userId}")
void deleteUserById(@Param("userId") String userId);
void insertUser(User user);
}
8.创建UserMapper.xml文件，放在
如果放在java的com.huang.mapper文件夹下，将不会自动加载，这个Idea有关系
9.创建配置类
package com.huang.config;
import org.apache.commons.dbcp.BasicDataSource;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
@Configuration
@MapperScan(basePackages = "com.huang.mapper")
public class DataConfig {
@Bean
public BasicDataSource dataSource(){
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8");//防止乱码
dataSource.setUsername("root");
dataSource.setPassword("huangyichun");
dataSource.setInitialSize(5);
dataSource.setMaxActive(10);
return dataSource;
}
@Bean
public DataSourceTransactionManager transactionManager() {
return new DataSourceTransactionManager(dataSource());
}
@Bean
public SqlSessionFactoryBean sqlSessionFactory() throws Exception {
SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setTypeAliasesPackage("com.huang.domain");
sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mapper/*.xml"));
return sessionFactory;
}
}
10.创建测试类
import com.huang.config.DataConfig;
import com.huang.domain.User;
import com.huang.mapper.UserMapper;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import java.util.List;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = DataConfig.class)
public class TestMybatis {
@Autowired
private UserMapper userMapper;
@Test
public void getUserById(){
User user = userMapper.getUserById("user0005");
System.out.println(user.toString());
}
@Test
public void getUserList(){
List<User> list = userMapper.getUserList();
for (User user : list){
System.out.println(user.toString());
}
}
@Test
public void updateUserEmailById(){
userMapper.updateUserEmailById("user0006","女");
}
@Test
public void deleteUserById(){
userMapper.deleteUserById("user0006");
}
@Test
public void insertUser(){
User user = new User();
user.setUserId("user0008");
user.setName("张三7");
user.setDepId("010102");
user.setSex("男");
userMapper.insertUser(user);
}
}
