使用mybatis-generator代码生成器时出现sql语句异常（这里的主要问题为数据库和表之间用了两个.）

org.springframework.jdbc.BadSqlGrammarException:

Error querying database. Cause: java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘.department’ at line 1

The error may exist in com/practice/springbootpracticemybatis/dao/DepartmentMapper.java (best guess)

The error may involve defaultParameterMap

The error occurred while setting parameters

SQL: SELECT did,dname,dpassword FROM interview…department

Cause: java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘.department’ at line 1

; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘.department’ at line 1

解决办法

在配置文件中，不要使用数据库加表的形式配置，直接给每个表配置

    <table catalog="interview" tableName="%">
        
        <generatedKey column="id" sqlStatement="Mysql" identity="true"/>
    table>

  

<table tableName="department" domainObjectName="Department">
    table>
    <table tableName="student" domainObjectName="Student">
    table>

虽然一个一个表设置是麻烦了点，但是稳啊

这里再附带上我的所有配置吧，毕竟是成功了

generatorConfig.xml配置文件

<generatorConfiguration>

<properties resource="jdbc.properties"/>

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

    
    <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
        <property name="mappers" value="com.practice.springbootpracticemybatis.tk.mybatis.MyMapper"/>
    plugin>

    
    <jdbcConnection
            driverClass="${jdbc.driverClass}"
            connectionURL="${jdbc.connectionURL}"
            userId="${jdbc.username}"
            password="${jdbc.password}">
    jdbcConnection>

    
    <javaModelGenerator targetPackage="com.practice.springbootpracticemybatis.entity" targetProject="src/main/java"/>

    
    <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources/generator"/>

    
    <javaClientGenerator
            targetPackage="com.practice.springbootpracticemybatis.dao"
            targetProject="src/main/java"
            type="XMLMAPPER"/>

    
    <table tableName="department" domainObjectName="Department">
    table>
    <table tableName="student" domainObjectName="Student">
    table>
