java.lang.ClassNotFoundException : org. glassfish.jersey.internal.RuntimeDelegateImpl ，抛出 BadRequestException 时

Question

我的 springbootapp 中有一个处理程序类，它对传入的 REST 请求执行一些验证，并将 BadRequestException 抛出回 Controller 类。

但是 Controller 不是捕获 BadRequestException，而是捕获 Exception 并抛出

java.lang.ClassNotFoundException: org.glassfish.jersey.internal.RuntimeDelegateImpl

我花了一些时间四处寻找解决方案，但似乎没有找到任何解决方案。

这是我在处理程序中的验证代码

    private void validateSignUpRequest(String phone) {
    if(StringUtils.isEmpty(phone))
        throw new BadRequestException("Phone Number can't be empty");
}

这是 Controller

@PostMapping(path = "/users/sign-up")
public ResponseEntity<UserData> signUpUser(@RequestBody Users user) {
    UserData userData = null;
    HttpStatus httpStatus = null;
    boolean flag = false;
    try {
        userData = userHandler.fetchByPhone(user.getPhoneNumber());
        if (userData == null) {
            flag = userHandler.saveUser(user);
            httpStatus = HttpStatus.CREATED;
        } else {
            userData = UserData.failureResponse("User Already Exist");
            httpStatus = HttpStatus.CONFLICT;
        }
    }catch(BadRequestException e) {
        userData = UserData.failureResponse(e.getMessage());
        httpStatus = HttpStatus.BAD_REQUEST;
    }
    catch (Exception e) {
        userData = UserData.failureResponse(e.getMessage());
        httpStatus = HttpStatus.INTERNAL_SERVER_ERROR;
    }
    return new ResponseEntity<>(userData,httpStatus);
}

该类https://github.com/jersey/jersey/blob/master/core-common/src/main/java/org/glassfish/jersey/internal/RuntimeDelegateImpl.java位于 jersey-common 下。

您缺少jersey-common https://mvnrepository.com/artifact/org.glassfish.jersey.core/jersey-common

    <dependency>
       <groupId>org.glassfish.jersey.core</groupId>
       <artifactId>jersey-common</artifactId>

    </dependency>
