1、配置

在Application添加注解：@MapperScan(basePackages = "com.zshanjun.library.upload.dao")
同时要注意，引进的包是tk.mybatis.spring.annotation.MapperScan

2、添加生成代码的助手类

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

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;

public class GeneratorDisplay {

    public void generator() throws Exception{

        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        //指定 逆向工程配置文件
        File configFile = new File("generatorConfig.xml");
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(configFile);
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(null);

    }

    public static void main(String[] args) throws Exception {
        try {
            GeneratorDisplay generatorSqlmap = new GeneratorDisplay();
            generatorSqlmap.generator();
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

添加了助手类后，还要在pom中添加mysql的依赖：

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.41</version>
        </dependency>

然后就可以通过运行助手类来生成代码了
