获得servletAPI

ActionContext

        //session域
        Map session = ActionContext.getContext().getSession();
        session.put("name", "session");

        //application域
        Map application = ActionContext.getContext().getApplication();
        application.put("name", "application");

        //request域
        //Map request = (Map) ActionContext.getContext().get("request");
        ActionContext.getContext().put("name", "request");

ServletActionContext

        HttpServletRequest request = ServletActionContext.getRequest();
        request.getSession();

        ServletActionContext.getResponse();

        ServletActionContext.getServletContext();

实现接口方式

package com.company.api;

import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class APIDemo3 extends ActionSupport implements ServletRequestAware, ServletResponseAware {

    private HttpServletRequest request;
    private HttpServletResponse httpServletResponse;

    @Override
    public String execute() throws Exception {

        return SUCCESS;
    }

    @Override
    public void setServletRequest(HttpServletRequest httpServletRequest) {
        this.request = request;
    }

    @Override
    public void setServletResponse(HttpServletResponse httpServletResponse) {
        this.httpServletResponse = httpServletResponse;
    }
}

参数封装

属性驱动

Parm

package com.company.param;

import com.opensymphony.xwork2.ActionSupport;

import java.util.Date;

public class Param extends ActionSupport {

    //与参数键名称相同的属性
    private String name;
    private Date birthday;
    private Integer age;


    @Override
    public String execute() throws Exception {

        System.out.println("name:" + name);
        System.out.println("birthday:" + birthday);
        System.out.println("age:" + age);

        return SUCCESS;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }
}
