IDEA插件之mybatisx 插件使用教程
作者:o_瓜田李下_o
MybatisX 是一款基于 IDEA 的快速开发插件,为效率而生。今天给大家介绍下mybatisx 插件使用。
mybatisx 插件使用
官网:https://baomidou.com/pages/ba5b24
插件安装
file ==> preferences ==> plugins:搜索mybatisx,安装插件
mybatisx 功能:
文件跳转:点击图标,可实现mapper接口、对应xml之间的互相跳转,serverImpl层跳转到注入的mapper接口
代码自动生成:根据表自动生成实体类、mapper接口、mapper xml、service、serverImpl类,模板可自定义
mapper方法自动填充:mapper接口中输入部分方法名,可自动补全代码,并在对应的mapper xml中生成sql语句
自动生成代码
连接数据源
mybatisx-generator 自动生成代码
说明:实体类的包名、类名,moduler path、base path、package name均可手动编辑
查看自动生成的代码
文件跳转
mapper接口:点击图标,跳转mapper xml文件
mapper xml:点击图标,跳转到mapper接口
PersonServiceImpl:点击图标,跳转到mapper接口
代码自动补全
mapper 接口写出方法名 ==> 右击 ==> show context actions
generate mybatis sql
mapper xml生成的sql
<?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.example.demo.mapper.PersonMapper"> <resultMap id="BaseResultMap" type="com.example.demo.pojo.Person"> <id property="id" column="id" jdbcType="INTEGER"/> <result property="name" column="name" jdbcType="VARCHAR"/> <result property="age" column="age" jdbcType="INTEGER"/> </resultMap> <sql id="Base_Column_List"> id,name,age </sql> <!-- mapper xml自动生成的sql语句 --> <select id="selectAllByName" resultMap="BaseResultMap"> select <include refid="Base_Column_List"/> from person where name = #{name,jdbcType=VARCHAR} </select> </mapper>
自动补全操作示例
自定义模板
mybatisx 模板:可对模板(ftl)进行修改、并恢复默认设置
.meta.xml
<?xml version="1.0" encoding="utf-8" ?> <templates> <template> <property name="configName" value="serviceInterface"/> <property name="configFile" value="serviceInterface.ftl"/> <property name="fileName" value="${domain.fileName}Service"/> <property name="suffix" value=".java"/> <property name="packageName" value="${domain.basePackage}.service"/> <property name="encoding" value="${domain.encoding}"/> <property name="basePath" value="${domain.basePath}"/> </template> <template> <property name="configName" value="serviceImpl"/> <property name="configFile" value="serviceImpl.ftl"/> <property name="fileName" value="${domain.fileName}ServiceImpl"/> <property name="suffix" value=".java"/> <property name="packageName" value="${domain.basePackage}.service.impl"/> <property name="encoding" value="${domain.encoding}"/> <property name="basePath" value="${domain.basePath}"/> </template> <template> <property name="configName" value="mapperInterface"/> <property name="configFile" value="mapperInterface.ftl"/> <property name="fileName" value="${domain.fileName}Mapper"/> <property name="suffix" value=".java"/> <property name="packageName" value="${domain.basePackage}.mapper"/> <property name="encoding" value="${domain.encoding}"/> <property name="basePath" value="${domain.basePath}"/> </template> <template> <property name="configName" value="mapperXml"/> <property name="configFile" value="mapperXml.ftl"/> <property name="fileName" value="${domain.fileName}Mapper"/> <property name="suffix" value=".xml"/> <property name="packageName" value="mapper"/> <property name="encoding" value="${domain.encoding}"/> <property name="basePath" value="src/main/resources"/> </template> </templates>

mapperXml.ftl

模版文件恢复为默认设置
