关于从页面获取数据到Action 的问题，求大神帮忙看看

只看楼主收藏回复

下面是代码
Project 实体类
@Entity
public class Project {
//项目id
@Id
@GeneratedValue()
@Column(name="project_id")
private int project_id;
//===================================================
//项目名称
@Column(name="project_name",length=50)
private String project_name;
//===================================================
//客户id(外键)
@ManyToOne(fetch=FetchType.LAZY) //
@JoinColumn(name="customer_id")
private Customer customer;
//===================================================

    Action 代码
    // 项目添加
    HttpServletRequest request = ServletActionContext.getRequest();
    @Resource(name="projectService")
    private ProjectService projectService;
    private Project project;
    private Demand demand;
    public Demand getDemand() {
    return demand;
    }
    public void setDemand(Demand demand) {
    this.demand = demand;
    }
    public void setProject(Project project) {
    this.project = project;
    }
    public String baseAdd(){
    String customer = request.getParameter("customer");
    /*String mustomer_name = request.getParameter("mustomer_name");*/
    String manager = request.getParameter("manager");
    String project_rank = request.getParameter("project_rank");
    System.out.println(customer);
    int p = Integer.parseInt(project_rank);
    System.out.println("ss");
    Customer c = customerQuery(customer);
    Staff m = managerQuery(manager);
    project.setCustomer(c);
    project.setManager(m);
    project.setProject_level(p);
    System.out.println(project.getProject_budget());
    int i = projectService.baseAdd(project);
    if(i != 0){
    return "base_queryAll";
    }
    return "base_Add";
    }
    //查询客户ID
    public Customer customerQuery(String customer){
    System.out.println("查询客户ID");
    return projectService.customerQuery(customer);
    }
    //查询人员ID
    public Staff managerQuery(String manager){
    System.out.println("查询人员ID");
    return projectService.managerQuery(manager);
    }

      还有实现类代码
      @Transactional(propagation=Propagation.NOT_SUPPORTED)
      public int baseAdd(Project project) {
      System.out.println("执行了daoimpl中的baseAdd方法");
      sessionFactory.getCurrentSession().persist(project);
      return 1;
      }
      @Transactional(propagation=Propagation.NOT_SUPPORTED)
      public Customer customerQuery(String customer) {
      Customer c= (Customer) sessionFactory.getCurrentSession().createQuery("from Customer where mustomer_company=?").setString(0, customer);
      return c;
      }
      @Transactional(propagation=Propagation.NOT_SUPPORTED)
      public Staff managerQuery(String manager) {
      Staff m= (Staff) sessionFactory.getCurrentSession().createQuery("from Staff where staff_name=?").setString(0, manager);
      return m;
      }

          由于实体类中有外键，用直接实体类的对象通过get,set方法获取是会出错，实体类中有两个字段的类型是对象，求大神告知如何解决这个问题
