自动创建JavaBean与mapper

1.配置：

1.1 resource (application.properties)

//标红的记得改

## 数据源配置
spring.datasource.url=jdbc:mysql://localhost:3306/20181020db?useUnicode=true&characterEncoding=utf8
spring.datasource.username=
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
## Mybatis 配置
mybatis.typeAliasesPackage=com.czxy.domain
mybatis.mapperLocations=classpath:com/czxy/dao/*.xml
## Mapper 配置
mapper.plugin=tk.mybatis.mapper.generator.MapperPlugin
mapper.Mapper=tk.mybatis.mapper.common.Mapper
mapper.mappers=com.czxy.utils.MapperUtils
mapper.not-empty=false
mapper.identity=MYSQL
## PageHelper
pagehelper.helperDialect=mysql
pagehelper.reasonable=true
pagehelper.supportMethodsArguments=true
pagehelper.params=count=countSql

spring.activemq.broker-url=tcp://localhost:61616
spring.activemq.in-memory=false
spring.activemq.pool.enabled=false
spring.activemq.user=admin
spring.activemq.password=admin

1.2 resource (config.properties)

# 数据库配置
mysql.driver=com.mysql.jdbc.Driver
mysql.url=jdbc:mysql://localhost:3306/20181020db?useUnicode=true&characterEncoding=UTF-8
mysql.username=
mysql.password=
# 通用Mapper配置
mapper.plugin=tk.mybatis.mapper.generator.MapperPlugin
mapper.Mapper=com.czxy.utils.MapperUtils
#  Java接口和实体类
targetJavaProject=src/main/java
targetModelPackage=com.czxy.domain
#  Mapper 生成路径
targetMapperProject=src/main/java
targetMapperPackage=com.czxy.dao
# Mapper XML 生成路径
targetResourcesProject=src/main/resources
targetXMLPackage=com.czxy.dao
# 指定要生成的表名 %为所有表 单表，请指定表名
targetTableName=t_cen

1.3 resource (generatorConfig.xml)

不用修改：

<generatorConfiguration>
    <properties resource="config.properties"/>

    <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <plugin type="${mapper.plugin}">
            <property name="mappers" value="${mapper.Mapper}"/>
        plugin>

        <jdbcConnection driverClass="${mysql.driver}"
                        connectionURL="${mysql.url}"
                        userId="${mysql.username}"
                        password="${mysql.password}">
        jdbcConnection>

        <javaModelGenerator targetPackage="${targetModelPackage}" targetProject="${targetJavaProject}"/>

        <sqlMapGenerator targetPackage="${targetXMLPackage}"  targetProject="${targetResourcesProject}"/>

        <javaClientGenerator targetPackage="${targetMapperPackage}" targetProject="${targetMapperProject}" type="XMLMAPPER" />

        <table tableName="${targetTableName}" >
            <generatedKey column="id" sqlStatement="Mysql" identity="true"/>
        table>
    context>
generatorConfiguration>

4 点击生成！

！整合maven分模块项目报错

1.1 报错信息

1.2 解决方案

因为他报我的service 依赖问题 因为我最外层的父项目也是springboot 所以生成会有问题，
因此我选择把我的service的依赖先加了注释（执行完生成 再把注释解了就好）
