本文主要是介绍mybatis插件生成实体类带有注释（表中Comment字段）的方法-oracle数据库，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
因为在工作中需要将生成的entity类带有注释信息，方便开发者查看字段属性，所以查找半天，并通过查看源码发现，其实很简单，代码如下：资源下载地址
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.1.2.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.example</groupId><artifactId>demo</artifactId><version>0.0.1-SNAPSHOT</version><name>demo</name><description>Demo project for mybatis generator</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>com.oracle</groupId><artifactId>ojdbc6</artifactId><version>11.2.0.3.0</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- mybatis生成 jar包 --><dependency><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-core</artifactId><version>1.3.7</version><scope>test</scope></dependency><dependency><groupId>commons-lang</groupId><artifactId>commons-lang</artifactId><version>2.6</version></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>1.3.2</version></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>
通过实体类main方法，生成entity、dao、xml：
public static void main(String[] args) throws Exception {List<String> warnings = new ArrayList<String>();boolean overwrite = true;ConfigurationParser cp = new ConfigurationParser(warnings);Configuration config = cp.parseConfiguration(MyBatisGen.class.getClassLoader().getResourceAsStream("generatorConfig.xml"));// 解决IDEA下运行，多个模块路径冲突问题String cpath = MyBatisGen.class.getClassLoader().getResource("generatorConfig.xml").toString();cpath = cpath.substring(0, cpath.indexOf("target")).replace("file:/", "");Context context = config.getContexts().get(0);context.getJavaModelGeneratorConfiguration().setTargetProject(cpath+context.getJavaModelGeneratorConfiguration().getTargetProject());context.getSqlMapGeneratorConfiguration().setTargetProject(cpath+context.getSqlMapGeneratorConfiguration().getTargetProject());context.getJavaClientGeneratorConfiguration().setTargetProject(cpath+context.getJavaClientGeneratorConfiguration().getTargetProject());DefaultShellCallback callback = new DefaultShellCallback(overwrite);MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);myBatisGenerator.generate(null);}
