spring boot+mybatis逆向生成

1.添加依赖

        
        
            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            1.3.2
        
          
        
            org.mybatis.generator
            mybatis-generator-core
            1.3.3
        

2.自定义注释生成器



import org.mybatis.generator.api.IntrospectedColumn;
import org.mybatis.generator.api.IntrospectedTable;
import org.mybatis.generator.api.dom.java.Field;
import org.mybatis.generator.internal.DefaultCommentGenerator;
import org.mybatis.generator.internal.util.StringUtility;

import java.util.Properties;

/**
 * 自定义注释生成器
 * Created by macro on 2018/4/26.
 */
public class CommentGenerator extends DefaultCommentGenerator {
    private boolean addRemarkComments = false;

    /**
     * 设置用户配置的参数
     */
    @Override
    public void addConfigurationProperties(Properties properties) {
        super.addConfigurationProperties(properties);
        this.addRemarkComments = StringUtility.isTrue(properties.getProperty("addRemarkComments"));
    }

    /**
     * 给字段添加注释
     */
    @Override
    public void addFieldComment(Field field, IntrospectedTable introspectedTable,
                                IntrospectedColumn introspectedColumn) {
        String remarks = introspectedColumn.getRemarks();
        //根据参数和备注信息判断是否添加备注信息
        if(addRemarkComments&&StringUtility.stringHasValue(remarks)){
            //文档注释开始
            field.addJavaDocLine("/**");
            //获取数据库字段的备注信息
            String[] remarkLines = remarks.split(System.getProperty("line.separator"));
            for(String remarkLine:remarkLines){
                field.addJavaDocLine(" * "+remarkLine);
            }
            addJavadocTag(field, false);
            field.addJavaDocLine(" */");
        }
    }
}

2.用于生产MBG的代码(执行操作的代码)

import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;

import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;

/**
 * 用于生产MBG的代码
 * Created by macro on 2018/4/26.
 */
public class Generator {
    public static void main(String[] args) throws Exception {
        //MBG 执行过程中的警告信息
        List warnings = new ArrayList();
        //当生成的代码重复时,覆盖原代码
        boolean overwrite = true;
        //读取我们的 MBG 配置文件
        InputStream is = Generator.class.getResourceAsStream("/generatorConfig.xml");
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(is);
        is.close();

        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        //创建 MBG
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        //执行生成代码
        myBatisGenerator.generate(null);
        //输出警告信息
        for (String warning : warnings) {
            System.out.println(warning);
        }
    }
}

3.数据库连接配置文件(generator.properties)

jdbc.driverClass=oracle.jdbc.OracleDriver
jdbc.connectionURL=jdbc:oracle:thin:@localhost:3306:orcl
jdbc.userId=root
jdbc.password=root

4.生成策略配置文件
