Record problem once mybatis genertor use and mapper scan met

  This record applies initial contact mybatis, Great God ignored. . .

　Overall two parts:

　　1, code is automatically generated using mybatis genertor

　　2, mapper scan

 

1, code is automatically generated using mybatis genertor

　　First, add the pom in dependence

<dependency>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-core</artifactId>
    <version>1.3.6</version>
</dependency>

<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <configuration>
        <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
        <verbose>true</verbose>
        <overwrite>true</overwrite>
    </configuration>
</plugin>

generatorConfig.xml configured as follows

<? xml Version = "1.0" encoding = "UTF-8"?> 
<DOCTYPE generatorConfiguration! 
        the PUBLIC "- // mybatis.org//DTD the Configuration MyBatis Generator 1.0 // EN" 
        "http://mybatis.org/dtd /mybatis-generator-config_1_0.dtd "> 
<generatorConfiguration>

        <commentGenerator> 
            <Property name =" suppressDate "value = "true" /> 
            ! <- true if the automatically generated annotation removal: is: to false: NO ->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!-- 生成模型的包名和位置-->
        <javaModelGenerator targetPackage="com.lilacfover.mybatisgenertor.entity" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="to true "/>         <-! package name and location of the mapping file generation targetProject may also be configured to src / main / java ->
        </ javaModelGenerator>

        <sqlMapGenerator targetPackage = "Mapper" targetProject = "the src / main / Resources"> 
            <Property name = "enableSubPackages" = value "to true" /> 
        </ sqlMapGenerator> 
        <-! DAO generated name and location of the package -> 
        <javaClientGenerator = type "XMLMAPPER" targetPackage = "com.lilacfover.mybatisgenertor.dao" targetProject = "the src / main / Java"> 
            <Property name = "enableSubPackages" = value "to true" /> 
        </ javaClientGenerator> 
        <-! be generated tableName table is a database table or view name domainObjectName entity class name -> 
        <table tableName = "admin_user" domainObjectName = "the Admin" enableCountByExample = "to false"enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"/>
    </context>
</ generatorConfiguration> 

this configuration automatically generate clicks

 

 FIG finally generated as follows:

 

 

Then you can use directly, I'm here controler simply call for a moment:

 

 

2, mapper scan.

　　If the data source is not configured maven application.properties only then scanned in resources configured xml: mybatis.mapper-locations = classpath:. Mapper / * xml

　　But we will mapper java in this manner can not scan the need to configure the data source in the maven follows:

<resources>

    <resource>
        <directory>src/main/resources</directory>
        <filtering>true</filtering>
    </resource>
    <resource>
        <directory>src/main/java</directory>
        <includes>
            <include>**/*.xml</include>
        </includes>
    </resource>
</resources>

然后在配置中配置xml扫描路径为：mybatis.mapper-locations= classpath:com/lilacfover/mybatisgenertor/mapper/*.xml

另外还要在mapper中添加@mapper注解

本次说明的地方大部分是我在使用中遇见的一些问题，希望对初次使用的有所帮助
