（1）建立工程

（2）新增 jar pom.xml
新增:springboot 父， mysql連線，(mybatis， spring-mybatis springboot ,阿里連線池) ,
服務中心客戶端。

（3）編寫配置檔案Application.properties

配置釋出服務名，埠；配置中心地址；連線mysql 引數
#1 register server
#服務名
spring.application.name =themeMicroService
#服務埠
server.port =8021
#註冊中心地址
eureka.client.service-url.defaultZone=http://127.0.0.1:8001/eureka

spring.datasource.driver-class-name =com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/forum2?useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=false
spring.datasource.username= root
spring.datasource.password=
spring.datasource.initialize =true
init-db= true
logging.level.com.codingapi=debug
（4）編寫實體，dao和對映。
實體：
public class Theme {
private Integer id;
private String tName;
private String tDescription;
get set
}
Dao 和對映

/**
 * 查詢
 * 
 * @return
 */
@Select(value = "select *  from theme")
public List<Theme> 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);

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

@Service
public class ThemeServiceImpl implements ThemeService {br/>@Autowired
private ThemeDao themeDao;

@Override
public List<Theme> 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);// 儲存1
    return rs1;

}

（6）編寫控制層 br/>@RestController
public class ThemeController {

@Autowired
private ThemeService themeService;// 塊服務，第一個服務

// 1接受請求
@RequestMapping(value = "/getThemeList", method = RequestMethod.GET)
public List<Theme> getThemeList() {
    List<Theme> ThemeList = themeService.getThemeList();
    return ThemeList;
}

@RequestMapping(value = "/saveTheme", method = RequestMethod.GET)
public  int saveTheme() {
    Integer result = themeService.saveTheme("jwg2", "jwg2", 1); 
return   result 
}

@SpringBootApplication //spring boot應用程式br/>@EnableEurekaClient
@MapperScan("com.jh.dao")
public class ThemeMicroService {
public static void main(String[] args) {

    SpringApplication.run(ThemeMicroService.class, args);
}

//1環境
@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"));//使用者名稱
    dataSource.setPassword(env.getProperty("spring.datasource.password"));//密碼
    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;      
}
