struts2之Action与JSP相互数据传递

package com.loaderman.crm.action;

import com.loaderman.crm.entity.User;
import com.loaderman.crm.service.UserService;
import com.loaderman.crm.service.impl.UserServiceimp;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import org.apache.struts2.ServletActionContext;

import javax.servlet.http.HttpServletRequest;

public class AddUserAction extends ActionSupport implements ModelDriven<User> {
    private User user = new User();

    public String execute() throws Exception {
        System.out.println(user.toString());
        UserService studentService = new UserServiceimp();
        HttpServletRequest request1 = ServletActionContext.getRequest();
        String opr = request1.getParameter("opr");
        int n = 0;
        if (opr.equals("addUser")) {
            n = studentService.addUser(user);
        } else if (opr.equals("modifyUser")) {
            int id = Integer.parseInt(request1.getParameter("id"));
            user.setId(id);
            n = studentService.modifyUser(user);
        }
        if (n > 0) {
            return "getUserList";
        } else {
            return "addUser";
        }
    }

    @Override
    public User getModel() {
        return user;
    }
}

使用ModelDriven可以接收表单传递过来的表单数据

使用下面可接收单个参数的数据

HttpServletRequest request1 = ServletActionContext.getRequest();

String opr = request1.getParameter("opr");

下面可以实现将actio数据传递到jsp页面显示

package com.loaderman.crm.action;

import com.loaderman.crm.entity.Policy;
import com.loaderman.crm.service.PolicyService;
import com.loaderman.crm.service.impl.PolicyServiceimp;
import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.ServletActionContext;
import org.apache.struts2.interceptor.RequestAware;

import javax.servlet.http.HttpServletRequest;
import java.util.List;
import java.util.Map;

public class GetPolicyListAciton extends ActionSupport implements RequestAware {
    private Map<String, Object> request;
    public String execute() throws Exception {
        HttpServletRequest request1 = ServletActionContext.getRequest();
        System.out.println("GetPolicyListAciton");
        String name = request1.getParameter("name");
        System.out.println("name"+name);
        if (name!=null&&(!name.isEmpty())){
            System.out.println("查询部分");
            name =new String(name.getBytes("ISO8859-1"), "UTF-8");
            PolicyService stuService = new PolicyServiceimp();
            List<Policy> list = stuService.getPolicyMoreInfoByName(name);
            request.put("list", list);
        }else {
            PolicyService stuService = new PolicyServiceimp();
            List<Policy> list = stuService.getAllPolicy();
            request.put("list", list);
        }

        return "success";

    }

    @Override
    public void setRequest(Map<String, Object> request) {
        this.request = request;
    }
}
