Spring Rest - Lombok 错误：重复注释答案

【问题标题】：Spring Rest - Lombok error: Duplicate annotationSpring Rest - Lombok 错误：重复注释
【发布时间】：2020-09-18 08:38:11
【问题描述】：

我有一个简单的 Rest API 可以向电话号码发送消息。此 api 仅验证输入（电话、消息）并插入数据库
效果很好。
之后，我使用 Lombok 来简化我的源代码。
我只是将 Lombok 依赖项插入到 pom.xml 文件中（我没有使用任何 Lombok 的功能）
项目可以成功构建和运行，但它无法正常工作
当我调用 /send-mt api 时显示此错误：

java.lang.annotation.AnnotationFormatError: Duplicate annotation for class: interface javax.validation.constraints.Size: @javax.validation.constraints.Size(groups=[], min=0, message={javax.validation.constraints.Size.message}, max=15, payload=[])

这是我的控制器：

import com.ttsc.myproject.models.MtRequest;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.RestController;
...

@RequestMapping("/api/v1")
@RestController
@Validated
public class TestController {

    @PostMapping("/send-mt")
    @ResponseBody
    public MyApiResponse SendMt(
           @Validated @RequestBody MtRequest request
        ) {
       
        resp = paymentService.processSendMt(request);
        
        return resp;
    }
}

这是我的 MtRequest 课程

package com.ttsc.myproject.models;

import javax.validation.constraints.NotBlank;
import javax.validation.constraints.Size;

public class MtRequest extends PaymentApiRequest {
    
    @Size(max=15)
    private String msisdn;
    
    @NotBlank
    private String message;   
    
    public String toString() {
        return "{msisdn: "+ msisdn +", message: "+ message +"}";
    }
    public void setMsisdn(String msisdn) {
        this.msisdn = msisdn;
    }
    public String getMsisdn() {
        return msisdn;
    }
    public void setMessage(String message) {
        this.message = message;
    }
    public String getMessage() {
        return message;
    } 
}

似乎无法运行任何验证。
你能帮我解决这个问题吗？谢谢！

【问题讨论】：

请同时添加课程。
@AnishB。我刚刚编辑了我的问题，添加了类。
@Size属于哪个包
javax.validation.constraints.Size @AnishB.
可能是由于 TestController 类顶部重复的 Validated 注释，您可以尝试将其删除并检查吗？

标签： java spring spring-boot maven lombok

【解决方案1】：

我使用 Netbean IDE（8.0 和 8.2）

有时当我单击“构建”时会发生此错误

但是在我点击“clean & build”后它又可以正常工作了

我不知道为什么？无论如何，这也是解决这种情况的解决方案:(
