控制器代码

@Component
@Path("/user")
public class AccessControlController 
{
@Autowired  
private AccessControlService accessControlService;

public AccessControlService getAccessControlService() {
    return accessControlService;
}

public void setAccessControlService(AccessControlService     
accessControlService) {
    this.accessControlService = accessControlService;
}

@GET
@Path("/testJersey")
public String testJersey(){
    System.out.println("working");
    return "success";
}

服务层 - 定义了自动线路。它包含到DAO层的映射。我给出了注释。但仍然说豆没有找到。 可能存在一些问题相关的jar文件，例如版本冲突。

public class AccessControlService implements AccessControlServiceInf
{
@Autowired
private AccessControlDAOImp accessControlDAOImp;

public AccessControlDAOImp getAccessControlDAOImp() {
    return accessControlDAOImp;
}

public void setAccessControlDAOImp(AccessControlDAOImp accessControlDAOImp)      
{
    this.accessControlDAOImp = accessControlDAOImp;
}

2 个答案:

答案 0 :(得分：0)

从错误中可以看出这一点。当Spring尝试创建accessControlController bean时，会有一个@Autowire注释字段。 Spring查找类型为com.ccube.pod.service.AccessControlService的bean，但在Spring上下文中没有这种类型的bean。 检查为什么没有所需类型的bean。

答案 1 :(得分：0)

经过网络和堆栈溢出后的问题 我发现了错误，

我们必须将@service和@repository注释添加到服务和dao类中。
