spring-boot开发微信小程序后台（二）

spring-boot开发微信小程序后台

spring boot与mybatis整合,mybatis逆向工程生成pojo、mapper、dao

逆向工程目录结构：

pom.xml：

	4.0.0

		cn.zoubin
		0.0.1-SNAPSHOT

	mybatis-generatorConfig
	
	
		UTF-8
	
	
	
			
		
		
		    org.springframework.boot
		    spring-boot-starter-log4j
		    1.3.8.RELEASE
		
		
        
		
            com.alibaba
            druid
            1.1.0
        
        
            com.alibaba
            druid-spring-boot-starter
            1.1.0
        
        
        
            mysql
            mysql-connector-java
            5.1.41
        

        
		
		    org.mybatis.spring.boot
		    mybatis-spring-boot-starter
		    1.3.1
		
		
		
		    tk.mybatis
		    mapper-spring-boot-starter
		    1.2.4
		
		
		
		    com.github.pagehelper
		    pagehelper-spring-boot-starter
		    1.2.3
		
	
		
 		
            org.mybatis.generator
            mybatis-generator-core
            1.3.2
            compile
            true
        
	
	

 GeneratorDisplay：启动类，加载数据库文件。

package cn.zoubin.mybatis.utils;

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 warnings = new ArrayList();
		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();
		}
		
	}
}

MyMapper：固定接口，生成dao类的继承父类，不能被扫描。

package cn.zoubin.utils;

import tk.mybatis.mapper.common.Mapper;
import tk.mybatis.mapper.common.MySqlMapper;

public interface MyMapper extends Mapper, MySqlMapper {
    //TODO
    //FIXME 特别注意，该接口不能被扫描到，否则会出错
}

generatorConfiguration.xml：配置文件，有关数据库，生成内容都在里面。

在配置文件中配置好所有信息后，就可以启动启动类，生成的代码、类都在你指定的包内。
