maven mybatis 快速生成

1、添加pom.xml,获取依赖的jar包

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
4.0.0
com.bw30.aop

${basedir}/src/main/resources/generatorConfig.xml
true
true



mysql

${mysql-connector-java.version}


tk.mybatis
mapper
${mapper.version}

2.在src/main/resource 下面添加config.properties和generatorConfig.xml文件

config.properties 文件

mapper.plugin = tk.mybatis.mapper.generator.MapperPlugin

mapper.Mapper = tk.mybatis.mapper.common.Mapper

generatorConfig.xml 文件

 
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

enableSelectByExample="false" selectByExampleQueryId="false">

3 、写Student 类

package com.bw30.store.dao.model.pojo;


import javax.persistence.*;


import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@NoArgsConstructor
@Table(name="Student")
public class Student {
    @Column(name="id")
    private String id;
    @Column(name="name")
    private String name;
    @Column(name="age")
    private Integer age;
    @Column(name="address")
    private String address;

}

4、运行maven

点击项目右键，选择Run,然后选择maven build .. ,输入mybatis-generator:generate

可以生成StudentMapper.java和StudentMapper.xml

5、spring-dao.xml 书写

xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans  
    http://www.springframework.org/schema/beans/spring-beans-4.1.xsd  
    http://www.springframework.org/schema/mvc  
http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd
    http://www.springframework.org/schema/context  
    http://www.springframework.org/schema/context/spring-context-4.1.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop-4.1.xsd">




classpath:/application-dao.properties









































 
dialect=mysql
pageSizeZero=true








 
mappers=tk.mybatis.mapper.common.Mapper
ORDER=AFTER

application-dao.properties文件

jdbc.driver=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql://172.16.10.233:3306/test?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull
jdbc.user=scal_store
jdbc.password=123456
jdbc.maxPoolSize=50
jdbc.minPoolSize=20
jdbc.initialPoolSize=1
jdbc.maxIdleTime=50
jdbc.checkoutTimeout=10000
jdbc.acquireRetryAttempts=3
jdbc.idleConnectionTestPeriod=50
jdbc.maxStatements=20

6、获取SqlSessionFactory

  String resource = "applicationContext-dao.xml";
       
       ClassPathXmlApplicationContext xmlApplicationContext = new ClassPathXmlApplicationContext(resource);
       
       sqlSessionFactory = xmlApplicationContext.getBean("sqlSessionFactory", SqlSessionFactory.class);

              SqlSession openSession = sqlSessionFactory.openSession();

StudentMapper mapper = openSession.getMapper(StudentMapper.class);
 
List selectByExample = mapper.selectByExample(new Example(Student.class));
System.out.println(selectByExample.size());

openSession.close();
