Spring Boot 实现Restful webservice服务端示例代码

1.Spring Boot configurations

application.yml
spring:
 profiles:
 active: dev
 mvc:
 favicon:
  enabled: false
 datasource:
 driver-class-name: com.mysql.jdbc.Driver
 url: jdbc:mysql://localhost:3306/wit_neptune?createDatabaseIfNotExist=true&useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&transformedBitIsBoolean=true
 username: root
 password: 123456
 jpa:
 hibernate:
  ddl-auto: update
 show-sql: true

2.Spring Boot Application

WitApp.java

package org.witpool;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class WitApp
{
 public static void main(String[] args)
 {
  SpringApplication.run(WitApp.class, args);
 }
}

3.Rest Controller

WitUserRest.java

package org.witpool.rest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.witpool.common.enums.WitCode;
import org.witpool.common.model.bean.WitResult;
import org.witpool.common.model.po.WitUser;
import org.witpool.common.util.WitUtil;
import org.witpool.persist.WitRepository;
import org.witpool.service.WitService;

@RestController
@RequestMapping("/users")
public class WitUserRest
{
 private final static Logger log = LoggerFactory.getLogger(WitUserRest.class);
 @Autowired
 private WitRepository reposit;
 @Autowired
 private WitService service;
 
 @PostMapping
 public WitResult addUser(@RequestBody WitUser user)
 {
  return WitUtil.success(reposit.save(user));
 }
 
 @PostMapping(value = "/{number}")
 public WitResult addUsers(@PathVariable("number") Integer num)
 {
  if (num < 0 || num > 10)
  {
   log.error("The number should be [0, 10]");
   return WitUtil.failure(WitCode.WIT_ERR_INVALID_PARAM);
  }
  return WitUtil.success(service.addUsers(num));
 }
 
 @PutMapping
 public WitResult updateUser(@RequestBody WitUser user)
 {
  return WitUtil.success(reposit.save(user));
 }
 
 @DeleteMapping(value = "/{userId}")
 public WitResult deleteUser(@PathVariable("userId") Integer userId)
 {
  reposit.delete(userId);
  return WitUtil.success();
 }
 
 @GetMapping(value = "/{userId}")
 public WitResult getUserByID(@PathVariable("userId") Integer userId)
 {
  return WitUtil.success(reposit.findOne(userId));
 }
 
 @GetMapping(value = "/name/{userName}")
 public WitResult getUserByName(@PathVariable("userName") String userName)
 {
  return WitUtil.success(reposit.findByUserName(userName));
 }
 
 @GetMapping
 public WitResult getUsers()
 {
  return WitUtil.success(reposit.findAll());
 }
}

4.Aspect

WitAspect.java

package org.witpool.common.aspect;
import javax.servlet.http.HttpServletRequest;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

@Aspect
@Component
public class WitAspect 
{
 private final static Logger log = LoggerFactory.getLogger(WitAspect.class);
 @Pointcut("execution(public * org.witpool.rest.WitUserRest.*(..))")
 public void log()
 {
 }
 @Before("log()")
 public void doBefore(JoinPoint jp)
 {
  ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
  HttpServletRequest req = attr.getRequest();
  // URL
  log.info("WIT: URL={}", req.getRequestURL());
  // Method
  log.info("WIT: HTTP Method={}", req.getMethod());
  // IP
  log.info("WIT: IP={}", req.getRemoteAddr());
  // 类方法
  log.info("WIT: REST CLASS={}", jp.getSignature().getDeclaringTypeName() + "." + jp.getSignature().getName());
  // 参数
  log.info("WIT: ARGS={}", jp.getArgs());
 }
 @After("log()")
 public void doAfter()
 {
  log.info("WIT: do after");
 }
 @AfterReturning(returning = "obj", pointcut = "log()")
 public void doAfterReturning(Object obj)
 {
  log.info("WIT: RESPonSE={}", obj.toString());
 }
}

5.Controller Advice

WitExceptHandle.java

package org.witpool.common.handle;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
import org.witpool.common.enums.WitCode;
import org.witpool.common.except.WitException;
import org.witpool.common.model.bean.WitResult;

@ControllerAdvice
public class WitExceptHandle
{
 private final static Logger logger = LoggerFactory.getLogger(WitExceptHandle.class);
 @ExceptionHandler(value = Exception.class)
 @ResponseBody
 public WitResult handle(Exception e)
 {
  if (e instanceof WitException)
  {
   WitException we = (WitException) e;
   return new WitResult(we.getCode(), we.getMessage());
  }
  else
  {
   logger.error(WitCode.WIT_ERR_INNER.getMsg() + "{}", e);
   return new WitResult(WitCode.WIT_ERR_INNER.getCode(), e.getMessage());
  }
 }
}

6.Jpa Repository

WitRepository.java

package org.witpool.persist;
import java.util.List;
import org.springframework.data.jpa.repository.JpaRepository;
import org.witpool.common.model.po.WitUser;

public interface WitRepository extends JpaRepository
{
 public List findByUserName(String userName);
}

7.代码下载、编译、打包

代码下载请访问 GitHub上的 witpool/Wit-Neptune

导入工程文件、编译、打包步骤如下：

Eclipse 导入maven工程

导入Maven工程

Maven打包

8.启动和UT步骤

启动应用：java -jar wit-rest-1.0.jar

UT步骤：

(1). 下载WisdomTool REST Client

(2). 双击 JAR包 restclient-1.1.jar 启动工具

导入测试用例文件：

关于WisdomTool REST Client更多的使用帮助，请参考GitHub wisdomtool/rest-client
