当我使用javax.annotation.ManagedBean时，Eclipse不会在EL中自动完成bean方法 [英] Eclipse won't autocomplete bean methods in EL when I use javax.annotation.ManagedBean

问题描述

我使用JSF和Spring创建了一个应用程序，我使用了@repository，@service @component和@autowired的注释，但是当我编写Facelet文件时，bean无法显示，任何人都可以帮助我

faces-config.xml：

ManagedBean：

 import javax.annotation.ManagedBean; 
 import javax.faces.bean.SessionScoped; 
 import org.springframework.beans.factory.annotation.Autowired;

 return headerButtonsDisabled; 
} 
 
 public void setHeaderButtonsDisabled（boolean headerButtonsDisabled）{
 this.headerButtonsDisabled = headerButtonsDisabled; 
} 
} 
  

解决方案

解决问题，问题是我在托管bean中导入错误的注释
导入错误：

  import javax.annotation.ManagedBean; 
  

正确导入：

  import javax.faces.bean.ManagedBean; 
  

所以结果：

  package com.tds.erp.managedController; 
 
 import java.util.ArrayList; 
 import java.util.List; 
 
 import javax.faces.bean.ManagedBean; 
 import javax.faces.bean.SessionScoped; 
 import org.springframework.beans.factory.annotation.Autowired; 
 import org.springframework.stereotype.Component; 
 
 import com.tds.erp.model.Employee; 
 import com.tds.erp.services.IEmployeeService; 
 
 
 @Component 
 @ManagedBean 
 @SessionScoped 
 public class EmployeeMB {
 
 
 
 @Autowired 
 private IEmployeeService EmployeService; 
 
 private Employee employee = new Employee（）; 
私人列表<员工> employeeList = new ArrayList< Employee>（）; 
 private Employee selectedEmployee = new Employee（）; 
 private boolean headerButtonsDisabled = true; 
 
 public void setEmployeService（IEmployeeService employeService）{
 EmployeService = employeService; 
} 
 
 public IEmployeeService getEmployeService（）{
 return EmployeService; 
} 
 ... 
  

I created an application using JSF and Spring and I used the annotations @repository, @service @component and @autowired but when I am coding the Facelet file the beans cannot show up, can any one help me

the ManagedBean :

import java.util.ArrayList;
import java.util.List;

import javax.annotation.ManagedBean;
import javax.faces.bean.SessionScoped;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.tds.erp.model.Employee;
import com.tds.erp.services.IEmployeeService;


@Component
@ManagedBean
@SessionScoped
public class EmployeeMB {

    @Autowired
    private IEmployeeService EmployeService;

    private Employee employee= new Employee();
    private List<Employee> employeeList= new ArrayList<Employee>();
    private Employee selectedEmployee=new Employee();
    private boolean headerButtonsDisabled=true;

    public void setEmployeService(IEmployeeService employeService) {
        EmployeService = employeService;
    }

    public IEmployeeService getEmployeService() {
        return EmployeService;
    }

    public Employee getEmployee() {
        return employee;
    }

    public void setEmployee(Employee employee) {
        this.employee = employee;
    }

    public List<Employee> getEmployeeList() {
        return employeeList;
    }

    public void setEmployeeList(List<Employee> employeeList) {
        this.employeeList = employeeList;
    }

    public Employee getSelectedEmployee() {
        return selectedEmployee;
    }

    public void setSelectedEmployee(Employee selectedEmployee) {
        this.selectedEmployee = selectedEmployee;
    }

    public boolean isHeaderButtonsDisabled() {
        return headerButtonsDisabled;
    }

    public void setHeaderButtonsDisabled(boolean headerButtonsDisabled) {
        this.headerButtonsDisabled = headerButtonsDisabled;
    }
}

解决方案

I solve the problem, and the problem is that I imported a wrong annotation in the managed bean the wrong import:

import javax.annotation.ManagedBean;

the right import:

import javax.faces.bean.ManagedBean;

so the result :

package com.tds.erp.managedController;

import java.util.ArrayList;
import java.util.List;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.tds.erp.model.Employee;
import com.tds.erp.services.IEmployeeService;


@Component
@ManagedBean
@SessionScoped
public class EmployeeMB {



    @Autowired
    private IEmployeeService EmployeService;

    private Employee employee= new Employee();
    private List<Employee> employeeList= new ArrayList<Employee>();
    private Employee selectedEmployee=new Employee();
    private boolean headerButtonsDisabled=true;

    public void setEmployeService(IEmployeeService employeService) {
        EmployeService = employeService;
    }

    public IEmployeeService getEmployeService() {
        return EmployeService;
    }
    ...
