The MyBatis reverse engineering tool automatically generates Java code based on database tables. Here are the steps to set up reverse engineering using MyBatis Generator.<\/p>\n
Create a Maven project or any other type of Java project.<\/p>\n
Add the dependency for the MyBatis Generator plugin in the project’s pom.xml file, such as:<\/p>\n
<dependency>\r\n <groupId>org.mybatis.generator<\/groupId>\r\n <artifactId>mybatis-generator-core<\/artifactId>\r\n <version>1.4.0<\/version>\r\n<\/dependency>\r\n<\/code><\/pre>\n3. Configuring the execution of the MyBatis Generator plugin in the project’s pom.xml file, for example:<\/p>\n
<build>\r\n <plugins>\r\n <plugin>\r\n <groupId>org.mybatis.generator<\/groupId>\r\n <artifactId>mybatis-generator-maven-plugin<\/artifactId>\r\n <version>1.4.0<\/version>\r\n <configuration>\r\n <configurationFile>src\/main\/resources\/generatorConfig.xml<\/configurationFile>\r\n <overwrite>true<\/overwrite>\r\n <verbose>true<\/verbose>\r\n <\/configuration>\r\n <executions>\r\n <execution>\r\n <id>Generate MyBatis Artifacts<\/id>\r\n <phase>generate-sources<\/phase>\r\n <goals>\r\n <goal>generate<\/goal>\r\n <\/goals>\r\n <\/execution>\r\n <\/executions>\r\n <dependencies>\r\n <dependency>\r\n <groupId>mysql<\/groupId>\r\n <artifactId>mysql-connector-java<\/artifactId>\r\n <version>8.0.24<\/version>\r\n <\/dependency>\r\n <\/dependencies>\r\n <\/plugin>\r\n <\/plugins>\r\n<\/build>\r\n<\/code><\/pre>\nCreate a configuration file named generatorConfig.xml under the src\/main\/resources directory in the project, to set up the generation rules for MyBatis Generator.<\/p>\n
5. Configure database connection information, table names, and the package name for generated Java code in the generatorConfig.xml file. For example:<\/p>\n
<generatorConfiguration>\r\n <context id=\"MyBatis3Simple\" targetRuntime=\"MyBatis3\">\r\n <jdbcConnection driverClass=\"com.mysql.cj.jdbc.Driver\"\r\n connectionURL=\"jdbc:mysql:\/\/localhost:3306\/test\"\r\n userId=\"root\"\r\n password=\"root\">\r\n <\/jdbcConnection>\r\n\r\n <javaModelGenerator targetPackage=\"com.example.model\"\r\n targetProject=\"src\/main\/java\">\r\n <\/javaModelGenerator>\r\n\r\n <sqlMapGenerator targetPackage=\"com.example.mapper\"\r\n targetProject=\"src\/main\/resources\">\r\n <\/sqlMapGenerator>\r\n\r\n <javaClientGenerator targetPackage=\"com.example.mapper\"\r\n targetProject=\"src\/main\/java\"\r\n type=\"XMLMAPPER\">\r\n <\/javaClientGenerator>\r\n\r\n <table tableName=\"user\"><\/table>\r\n <\/context>\r\n<\/generatorConfiguration>\r\n<\/code><\/pre>\nExecute the command ‘mvn mybatis-generator:generate’ in the command line, or in your IDE right-click on the project and select “Run As” -> “Maven Build”, then enter ‘mybatis-generator:generate’ as goals to run the command and generate code.<\/p>\n
The generated Java code will be automatically saved in the configured directory, allowing access to the database in the project using this generated code.<\/p>\n","protected":false},"excerpt":{"rendered":"
