InstanceServiceImpl中的构造函数的参数0需要一个InstanceRequest类型的bean，但找不到

Question

EC2InstanceApp.java：

@SpringBootApplication @ EnableSwagger2 @ComponentScan（basePackages =“ com.publicis.sapient.ppc.analyticstool.createec2instance”） 公共类EC2InstanceApp {

public static void main(String[] args) {

    SpringApplication.run(EC2InstanceApp.class, args);
}

}

InstanceServiceImpl-服务类

@服务 公共类InstanceServiceImpl实现InstanceService {

private InstanceRequest instanceRequest;

public InstanceServiceImpl(InstanceRequest instanceRequest) {

    this.instanceRequest = instanceRequest;
}

}

Bean类：

包com.publicis.sapient.ppc.analyticstool.createec2instance.model;

公共类InstanceRequest {

private String description;
private String type;
private String storage;
private String userId;
private Integer projectId;
private Integer clientId;

public String getType() {
    return type;
}

public void setType(String type) {
    this.type = type;
}

public String getStorage() {
    return storage;
}

public void setStorage(String storage) {
    this.storage = storage;
}

public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}

public String getUserId() {
    return userId;
}

public void setUserId(String userId) {
    this.userId = userId;
}

public Integer getProjectId() {
    return projectId;
}

public void setProjectId(Integer projectId) {
    this.projectId = projectId;
}

public Integer getClientId() {
    return clientId;
}

public void setClientId(Integer clientId) {
    this.clientId = clientId;
}

}

Ec2Controller.java：

@RequestMapping（方法= RequestMethod.POST，值=“ / instances”）     public InstanceResponse addInstance（@RequestBody InstanceRequest instanceRequest）{

    logger.info("propertyUrlDb : " + propertyUrlDb);

    String email = instanceRequest.getUserId();
    logger.info("Email id of the user : " + email);
    String instanceId = null;
    State state = new State();
    InstanceServiceImpl instanceServiceImpl = new InstanceServiceImpl(instanceRequest);
