Spring boot 與RestEasy結合

Spring boot 與RestEasy結合

Spring Boot 官方並沒有出於RestEasy結合的jar包，估計是應爲RestEasy用的比較少吧，但是paypal團隊出了一個jar(傳送門1)，估計他們那邊有RestEasy用的比較多吧，PayPal是國際版本的支付寶(傳送門2)

首先導包

<dependency>
   <groupId>com.paypal.springboot</groupId>
   <artifactId>resteasy-spring-boot-starter</artifactId>
   <version>2.3.3-RELEASE</version>
   <scope>runtime</scope>
</dependency>

然後定義一個JAX-RS格式的應用類（application 繼承javax.ws.rs.core.Application）
然後作爲Spring的bean來註冊就好了

package com.sample.app;

import org.springframework.stereotype.Component;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@Component
@ApplicationPath("/sample-app/")
public class JaxrsApplication extends Application {

}

````

RestEasy 的resources 和providers 只要聲明爲Spring 的Bean，它就是會自動註冊


然後在Spring boot的配置文件中配置Application.property文件裏面設置 resteasy.jaxrs.app.registration 
讓他是否自動註冊，取值有

1. beans 
1. property
1. scanning
1. auto (default)

ReatEasy 校驗參數，全局處理返回結果

先添加jar包




<div class="se-preview-section-delimiter"></div>

org.jboss.resteasy
resteasy-validator-provider-11
3.1.4.Final

這個包主要是將hibernate-validator和RestEasy全局異常處理接口ExceptionMapping結合使用 
首先實現全局validator異常處理




<div class="se-preview-section-delimiter"></div>

package com.hey900.oa.filter;

import com.hey900.oa.Result;
import org.jboss.resteasy.api.validation.ResteasyConstraintViolation;
import org.jboss.resteasy.api.validation.ResteasyViolationException;
import org.springframework.stereotype.Component;

import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;
import java.util.List;

/**
* Created with IntelliJ IDEA.
* Description:
* UserVO:劉敏華 [email protected]
* DateDeserializer: 2017-08-08
* Time: 13:44
*/
@Component
@Provider
public class ParamMapping implements ExceptionMapper {

@Override
public Response toResponse(ResteasyViolationException  restEasyViolationException ) {
    List<ResteasyConstraintViolation> violations = restEasyViolationException.getViolations();
    ResteasyConstraintViolation resteasyConstraintViolation = null;
    if(violations!=null&&!violations.isEmpty()){
        resteasyConstraintViolation = violations.get(0);
    }
    return Response.ok(Result.fail(resteasyConstraintViolation.getMessage()), MediaType.APPLICATION_JSON_TYPE).build();
}

}

然後使用





<div class="se-preview-section-delimiter"></div>

/**
* Created with IntelliJ IDEA.
* Description:
* UserVO:劉敏華 [email protected]
* DateDeserializer: 2017-08-08
* Time: 14:18
*/
public class UserParam {

@NotNull(message = "用戶名不能爲空")
private String name;

@Pattern(regexp = "^[a-zA-Z0-9_.-][email protected]",message = "請輸入正確的公司郵箱")
@ApiModelProperty("員工郵箱")
private String email;

@NotNull(message = "手機號不能爲空")
@Size(min = 11,max=11,message = "請填寫合法的手機號")
private String phone;

@NotNull(message = "登錄密碼不能爲空")
@Size(min = 6,max=20,message = "密碼長度需要再6~20位字符之間")
private String password;

@NotNull(message = "入職日期不能爲空")
@JsonDeserialize(using = DateDeserializer.class)
private Date entryDate;

@NotNull(message = "轉正日期不能爲空")
@JsonDeserialize(using = DateDeserializer.class)
private Date regularDate;

@JsonDeserialize(using = DateDeserializer.class)
private Date leaveDate;

在Api裏面校驗





<div class="se-preview-section-delimiter"></div>

@Secured(resource = "user.add",name = "新增用戶")
@POST
@Path("/add")
@ApiOperation("用戶增加接口")
public Result<UserVO> add(@Valid UserParam userParam)
{
    return userService.add(userParam);
}
