Hiện tại tôi đang gặp sự cố trong cấu hình Autowire giữa bộ điều khiển và lớp dịch vụ.@Autowired - Không có loại đậu đủ điều kiện được tìm thấy cho phụ thuộc ít nhất 1 bean
Tôi không thể theo dõi lỗi của mình.
Simple Log Info
SEVERE: Exception while loading the app
SEVERE: Undeployment failed for context /OTT
SEVERE: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException: org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type [com.ott.service.EmployeeService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}
Dưới đây tôi cũng đã đưa ra các điều khiển và dịch vụ lớp mã và cũng dispatcher-servlet.xml
khiển
package com.ott.controller;
import com.ott.service.EmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
*
* @author SPAR
*/
@Controller
public class AdminController {
private EmployeeService employeeService;
@RequestMapping("/employee")
public String employee(){
this.employeeService.fetchAll();
return "employee";
}
@Autowired(required = true)
@Qualifier(value="employeeService")
public void setEmployeeService(EmployeeService empService) {
this.employeeService = empService;
}
}
Giao diện dịch vụ
package com.ott.service;
import com.ott.hibernate.Employee;
import java.util.List;
/**
*
* @author SPAR
*/
public interface EmployeeService {
List<Employee> fetchAll();
}
Interface Dịch vụ Impl
package com.ott.service;
import com.ott.dao.EmployeeDAO;
import com.ott.hibernate.Employee;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;

@Service
public class EmployeeServiceImpl implements EmployeeService{
private EmployeeDAO employeeDAO;
@Override
@Transactional(readOnly = true)
public List<Employee> fetchAll() {
List<Employee> employees = employeeDAO.fetchAll();
for (Employee employee : employees) {
System.out.println("Name : "+employee.getFirst_Name() +" "+ employee.getLast_Name());
System.out.println("Email Id : "+employee.getEmail_Id());
}
return employees;
}
@Autowired(required = true)
@Qualifier(value="employeeDAO")
public void setEmployeeDAO(EmployeeDAO empDAO) {
this.employeeDAO = empDAO;
}

bạn có thể thêm @Service ("e mployeeService ") –
