JAX-RS/Jersey如何自定义错误处理？

public class CustomException extends RuntimeException {
    public CustomException(String message) {
        super(message);
    }
}

import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;

public class CustomExceptionMapper implements ExceptionMapper<CustomException> {
    @Override
    public Response toResponse(CustomException exception) {
        // 自定义错误处理逻辑
        return Response.status(Response.Status.BAD_REQUEST)
                .entity("自定义错误处理信息")
                .type("text/plain")
                .build();
    }
}

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/custom")
public class CustomResource {
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String throwCustomException() {
        throw new CustomException("触发自定义错误处理");
    }
}
