我在我的项目中添加了@OrderBy,现在我收到以下错误:

我正在尝试使用 CDI 将 DAO 注入我的 ManagedBean

托管Bean：

import java.io.Serializable;

import javax.enterprise.context.RequestScoped;
import javax.inject.Inject;
import javax.inject.Named;

import br.com.timbrasil.network.dao.ColaboradorDao;
import br.com.timbrasil.network.modelo.Colaborador;

@SuppressWarnings("serial")
@Named
@RequestScoped
public class LoginBean implements Serializable{

    private Colaborador colaborador = new Colaborador();
    @Inject
    private ColaboradorDao dao;

道

import java.io.Serializable;

import javax.enterprise.context.RequestScoped;
import javax.inject.Inject;
import javax.persistence.EntityManager;
import javax.persistence.TypedQuery;

import br.com.timbrasil.network.modelo.Colaborador;

@SuppressWarnings("serial")
@RequestScoped
public class ColaboradorDao implements Serializable{

    @Inject
    private EntityManager manager;

    public Colaborador buscaEmailESenha(Colaborador colaborador) {

        String jqpl = "select c from Colaborador c where c.email = :pEmail and c.senha …

private String path;

因此,当我使用路径时,它具有属性文件中的值,而不是彻底读取属性和获取值的整个过程.
