java-mybatis generator 后不要覆盖原来的mapper文件中自己手写的部分。—

mybatis generator生成的mapper.xml文件问题

<where > <foreach collection="example.oredCriteria" item="criteria" separator="or" > <if test="criteria.valid" > <trim prefix="(" suffix=")" prefixOverrides="and" > <foreach collection="criteria.criteria" item="criterion" > <choose > <when test="criterion.noValue" > and ${criterion.condition} </when> <when test="criterion.singleValue" > and ${criterion.condition} #{criterion.value} </when> 第三行代码中的<if test="criteria.valid">我在Criteria这个类中根本没有发现有valid这个属性，请问一下这里是怎么回事啊？

mybatis generator逆向生成后的错误

generator逆向生成的mapper接口文件全部报错，显示生成的pojo类cannot be resolved

【mybatis generator的报错】前期配置问题！！！！！官方文件看了一直也一头雾水

错误如下 Description Resource Path Location Type The content of element type "context" must match "(property*,plugin*,commentGenerator?,(connectionFactory|jdbcConnection),javaTypeResolver?,javaModelGenerator,sqlMapGenerator?,javaClientGenerator?,table+)". generatorConfig.xml /oracle/generator line 4 XML Problem 指向的代码错误是这样的 ``` <generatorConfiguration> <context id="oracleTables" defaultModelType="hierachical" targetRuntime="MyBatis3"> ``` 错误指向context id 改了半天一直报错。。难道是pom.xml的代码顺序问题？？补源代码 ``` <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <context id="oracleTables" defaultModelType="hierachical" targetRuntime="MyBatis3">  <property name="autoDelimitKeywords" value="false"/>  <property name="javaFileEncoding" value="UTF-8"/>  <property name="xmlFormatter" value="org.mybatis.generator.api.dom.DefaultXmlFormatter"/>  <property name="beginningDelimiter" value='"'/> <property name="endingDelimiter" value='"'/>  <jdbcConnection connectionURL="jdbc:oracle:thin:@localhost:1521:orcl" driverClass="oracle.jdbc.driver.OracleDriver" password="S123456" userId="c##refeal" />  <javaTypeResolver type="org.mybatis.generator.internal.types.JavaTypeResolverDefaultImpl"> <property name="forceBigDecimals" value="false"/> </javaTypeResolver>  <javaModelGenerator targetPackage="com.SJY.domain" targetProject="src/main/java" />  <property name="constructorBased" value="false"/>  <property name="enableSubPackages" value="true"/>  <property name="immutable" value="false"/>  <property name="rootClass" value="com.sjy.domain"/>  <sqlMapGenerator targetPackage="com.SJY.dao" targetProject="src/main/resources" />  <property name="enableSubPackages" value="true"/>  <javaClientGenerator targetPackage="com.SJY.domain" targetProject="src/main/java" type="XMLMAPPER" />  <property name="enableSubPackages" value="true"/>  <table schema="" tableName="SJY_YH_YHXXB" domainObjectName="YH_YHXXB" mapperName="YH_YHXXBMapper" enableUpdateByExample="true" enableDeleteByExample="true" enableSelectByExample="true" selectByExampleQueryId="true"> <generatedKey column="USERID" sqlStatement="SELECT SJY_YH_YHXXB_SEQUENCE.nextval AS USERID from DUAL"/> <columnOverride column="USERID" property="???" /> </table> </context> </generatorConfiguration> ``` 表字段暂时可以无视吧

spring boot 整合mybatis-generator如何搭建和配置

大家都在用什么mybatis代码生成器?

我们公司里统一规定,所有项目中使用的mybatis代码生成器,只能使用fwjava.com这个网站生成的代码. 以前常用的mybatis-generator或mybatis-mapper之类的,好像不让用了.说是sql代码质量不好... 大家都在用什么MyBatis或iBatis的代码生成器?也在用fwjava吗? 你们的公司里也有这类规定吗?

mybatis出现了很奇怪的问题

``` ### Error querying database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'card_id' in 'field list' ### The error may exist in com/ershou/mapper/UserMapper.xml ### The error may involve com.ershou.mapper.UserMapper.selectByExample-Inline ### The error occurred while setting parameters ### SQL: select card_id, password, college, grade, sex, status, trueName, image from user WHERE ( card_id = ? and password = ? ) ### Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'card_id' in 'field list' ; bad SQL grammar []; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'card_id' in 'field list'] with root cause com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'card_id' in 'field list' ``` 提示我的card_id 数据库不认识，但是我的数据库就是这样定义的啊我用的也是generator自动生成的代码 CREATE TABLE `user` ( `card_id` varchar(20) NOT NULL, `password` varchar(20) DEFAULT NULL, `college` varchar(200) DEFAULT NULL, `grade` varchar(200) DEFAULT NULL, `sex` int(2) DEFAULT '1', `status` int(2) DEFAULT '1', `trueName` varchar(20) DEFAULT NULL, `image` varchar(50) DEFAULT NULL, PRIMARY KEY (`card_id`) ) 看一下mybatis的XXXMapper.xml文件 <resultMap id="BaseResultMap" type="com.ershou.entity.User" > <id column="card_id" property="cardId" jdbcType="VARCHAR" /> <result column="password" property="password" jdbcType="VARCHAR" /> <result column="college" property="college" jdbcType="VARCHAR" /> <result column="grade" property="grade" jdbcType="VARCHAR" /> <result column="sex" property="sex" jdbcType="INTEGER" /> <result column="status" property="status" jdbcType="INTEGER" /> <result column="trueName" property="truename" jdbcType="VARCHAR" /> <result column="image" property="image" jdbcType="VARCHAR" /> </resultMap> <select id="selectByExample" resultMap="BaseResultMap" parameterType="com.ershou.entity.UserExample" > select <if test="distinct" > distinct </if> <include refid="Base_Column_List" /> from user <if test="_parameter != null" > <include refid="Example_Where_Clause" /> </if> <if test="orderByClause != null" > order by ${orderByClause} </if> </select> 哪里出错了见鬼了求大神

Spring Boot + Mybatis 配置多数据源出错

刚接触Spring Boot 不久，今天用 Spring Boot + Mybatis 按照网上的方法配置多数据源，配置了多个DataConfig，并给其中一个打上了Primary注解，现在出现这样的问题：给哪个数据源加Primary注解哪个数据源才能查询成功，其他的数据源一查就报异常，搞了好久不知道哪出的问题，各位大婶帮忙看看，下面是堆栈信息 org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderException: Error invoking SqlProvider method (tk.mybatis.mapper.provider.ExampleProvider.dynamicSQL).

return "succ"; }*/ } 4：UsernamePasswordToken 我没有这个类，这好像是一个方法-------网上好像说这是个认证机制，，不知道跳转不了跟这个有没有关系网上解释：是最常见的用户名/密码的认证机制;同时,由于它实现了RememberMeAuthenticationToken接口，我们可以通过令牌设置“记住我”的功能。但是，“已记住”和“已认证”是有区别的：已记住的用户仅仅是非匿名用户，你可以通过subject.getPrincipals()获取用户信息。但是它并非是认证通过的用户，当你访问需要认证用户的功能时，你仍然需要重新提交认证信息。这一区别可以参考淘宝网站，网站会默认记住登录的用户，再次访问网站时，对于非敏感的页面功能，页面上会显示记住的用户信息，但是当你访问网站账户信息时仍然需要再次进行登录认证。 5：我的自定义数据库配置“jdbc.properties”: driverClassName=com.mysql.jdbc.Driver validationQuery=SELECT 1 jdbc_url=jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false jdbc_username=root jdbc_password=1234 6:"generatorConfig.xml" 这个就是上面的数据库驱动的配置 <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" > <generatorConfiguration>   <classPathEntry location="D:\Users\lydia\workspaceSSH\shopCMS\src\main\webapp\WEB-INF\lib\mysql-connector-java-5.1.34.jar"/> <context id="MysqlTables" targetRuntime="MyBatis3">     <commentGenerator>  <property name="suppressAllComments" value="true"/> </commentGenerator>   <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/shop" userId="root" password="1234"> </jdbcConnection>    <javaTypeResolver> <property name="forceBigDecimals" value="false"/> </javaTypeResolver>    <javaModelGenerator targetPackage="com.coder520.user.entity" targetProject="D:\Develop\IDEAWorkPlace\work-attendance\src\main\java" >  <property name="enableSubPackages" value="true"/>  <property name="trimStrings" value="true"/> </javaModelGenerator>   <sqlMapGenerator targetPackage="com.coder520.user.dao" targetProject="D:\Users\lydia\workspaceSSH\shopCMS\src\main\java"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator>   <javaClientGenerator targetPackage="com.coder520.user.dao" targetProject="D:\Users\lydia\workspaceSSH\shopCMS\src\main\java" type="XMLMAPPER"> <property name="enableSubPackages" value="true"/> </javaClientGenerator>     <table tableName="role" domainObjectName="Role" enableInsert="true" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">     </table> <table tableName="permission" domainObjectName="Permission" enableInsert="true" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">     </table> </context> </generatorConfiguration> 万分感谢大佬，，，，，帮我解决这问题我就认你当师傅，，，大佬，，拜托了，，，还需要什么麻烦留下言哈

Java学习的正确打开方式

在博主认为，对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结，前三者博主将淋漓尽致地挥毫于这篇博客文章中，至于总结在于个人，实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍，博客次之，这又是一个层次了，这里暂时不提后面再谈。博主将为各位入门java保驾护航，各位只管冲鸭！！！上天是公平的，只要不辜负时间，时间自然不会辜负你。何谓学习？博主所理解的学习，它是一个过程，是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
