（1）创建工程

（2）添加 jar pom.xml

添加:springboot 父， mysql连接，(mybatis， spring-mybatis springboot ,阿里连接池) ,服务中心客户端。

         pom
                        
        
         import
                    
               
          
     
    

（3）编写配置文件Application.properties

配置发布服务名，端口；配置中心地址；连接mysql 参数

#1 register server #服务名spring.application.name =themeMicroService#服务端口server.port =8021#注册中心地址eureka.client.service-url.defaultZone=http://127.0.0.1:8001/eurekaspring.datasource.driver-class-name =com.mysql.jdbc.Driverspring.datasource.url=jdbc:mysql://localhost:3306/forum2?useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=falsespring.datasource.username= rootspring.datasource.password=spring.datasource.initialize =trueinit-db= truelogging.level.com.codingapi=debug

（4）编写实体，dao和映射。

实体：

public class Theme {private  Integer id;private  String  tName;private  String  tDescription;get set }

Dao 和映射

@Mapperpublic interface ThemeDao {    /**     * 查询     *      * @return     */    @Select(value = "select *  from theme")    public List
    
      getThemeList();    /**     * 插入     *      * @param bname     * @param bDescription     * @return     */    @Insert(value = "insert  into theme(tName,tDescription,blockId)" + " values(#{tName},#{tDescription},"            + "#{blockId})")    public int saveTheme(@Param("tName") String tName, @Param("tDescription") String tDescription,  @Param("blockId")  Integer blockId);}
    

（5）编写服务层

服务接口

public interface ThemeService {

List
    
      getThemeList();int saveTheme(String tName, String  tDescription , Integer blockId);
    

}

服务实现：

package com.jh.service.impl;@Servicepublic class ThemeServiceImpl implements ThemeService {    @Autowired    private ThemeDao themeDao;    @Override    public List
    
      getThemeList() {        return themeDao.getThemeList();    }    @Override    public int saveTheme(String tName, String tDescription, Integer blockId) {        // TODO Auto-generated method stub        int rs1 = themeDao.saveTheme(tName, tDescription, blockId);// 保存1        return rs1;    }}
    

（6）编写控制层

@RestControllerpublic class ThemeController {    @Autowired    private ThemeService themeService;// 块服务，第一个服务    // 1接受请求    @RequestMapping(value = "/getThemeList", method = RequestMethod.GET)    public List
    
      getThemeList() {        List
     
       ThemeList = themeService.getThemeList();        return ThemeList;    }    @RequestMapping(value = "/saveTheme", method = RequestMethod.GET)    public  int saveTheme() {        Integer result = themeService.saveTheme("jwg2", "jwg2", 1);     return   result     }}
     
    

（7） 编写主程序

开启springboot应用程序，注册中心客户端，mybatis扫描和定义一个数据源package com.jh;

@SpringBootApplication  //spring boot应用程序@EnableEurekaClient@MapperScan("com.jh.dao")public class ThemeMicroService {    public static void main(String[] args) {        SpringApplication.run(ThemeMicroService.class, args);    }    //1环境    @Autowired    private Environment env;    @Bean    public DataSource dataSource() {        DruidDataSource dataSource = new DruidDataSource();        dataSource.setUrl(env.getProperty("spring.datasource.url"));        dataSource.setUsername(env.getProperty("spring.datasource.username"));//用户名        dataSource.setPassword(env.getProperty("spring.datasource.password"));//密码        dataSource.setInitialSize(10);        dataSource.setMaxActive(50);        dataSource.setMinIdle(1);        dataSource.setMaxWait(60000);        dataSource.setValidationQuery("SELECT 1");        dataSource.setTestOnBorrow(false);        dataSource.setTestWhileIdle(true);        dataSource.setPoolPreparedStatements(false);        return dataSource;          }}

（8）测试

启动注册中心，启动微服务 然后启动浏览器
