Java 尝试在我的SpringREST应用程序的postman上使用put和post方法时出现500内部服务器错误

我尝试了xml和json。使用POST时，它会将null元素添加到列表中，并给出java.lang.NoClassDefFoundError异常。使用PUT时，我收到一个运行时异常。GET方法正在正常运行。你能帮我调试代码吗？ 以下是我的服务和控制器类

@Consumes("application/xml,application/json")
@Produces("application/xml,application/json")

    @Autowired
    private PatientService patientService;

    @GetMapping("patientservice/patients")

    }

    @GetMapping("patientservice/patients/{id}")
    Patient getPatient(@PathVariable("id") Long id ) {
        return patientService.getPatient(id);
    }

    @PostMapping("patientservice/patients" )
    Response createPatient(Patient patient) {
        return patientService.createPatient(patient);
    }

    @PutMapping("patientservice/patients")
    Response updatePatient(Patient patient) {
        return patientService.updatePatient(patient);
    }

看起来您缺少

@RequestBody

注释，该注释指示参数如何绑定到web请求

---

我不确定您是否正在构建ApacheCfx项目的spring项目。但是，如果您想使用SpringBoot创建服务，这对您的入门非常有用

PatientController.java

import org.springframework.web.bind.annotation.*;

@RestController
public class PatientController {



    @PostMapping("patientservice/patients" )
    Response createPatient(@RequestBody Patient patient) {
        System.out.println("createPatient"+patient.toString());
        return new Response("Sucess","200");
    }

    @PutMapping("patientservice/patients")
    Response updatePatient(@RequestBody Patient patient) {
        System.out.println("updatePatient"+patient.toString());
        return new Response("Sucess","200");
    }
}

Patient.java

public class Patient {

    String fName;
    String lName;
    String disease;

    public String getfName() {
        return fName;
    }

    public void setfName(String fName) {
        this.fName = fName;
    }

    public String getlName() {
        return lName;
    }

    public void setlName(String lName) {
        this.lName = lName;
    }

    public String getDisease() {
        return disease;
    }

    public void setDisease(String disease) {
        this.disease = disease;
    }

    @Override
    public String toString() {
        return "Patient{" +
                "fName='" + fName + '\'' +
                ", lName='" + lName + '\'' +
                ", disease='" + disease + '\'' +
                '}';
    }
}

在spring boot的主类上，必须使用注释，如

@ComponentScan（“com.your.package”）
