<!--配置Spring包扫描-->

<!--处理器映射器，处理器适配器，需要开启MVC-->
<mvc:annotation-driven/>
<!--配置MVC对静态资源放行-->
<!--对static文件下的所有目录文件放行-->
<mvc:resources mapping="static/**" location="/static/"/>
<!--配置视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

webapp下的index.jsp文件
<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<body>
<%--action在直接写/需要加相对路径--%>
<h2>信息提交</h2>
<form action="threadController.do" method="get">

总集合的配置
package com.msb.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.util.List;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class ListArrays {
private List<Pet> pets;
private List<Persion> persions;
}
子集合的配置
//人类
package com.msb.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.format.annotation.DateTimeFormat;
import java.util.Date;
import java.util.List;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Persion {
private Integer id;
private String name;
private String password;
private List[] hobby;
@DateTimeFormat(pattern = "yyyy-MM-dd")
private Date birthday;
}
//宠物类
package com.msb.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.util.List;
@NoArgsConstructor
@AllArgsConstructor
@Data
public class Pet {
private String Petname;
private String Petanimal;
}
访问跳转配置Controller
package com.msb.controller;
import com.msb.pojo.ListArrays;
import com.msb.pojo.Persion;
import com.msb.pojo.Pet;
import jdk.nashorn.internal.ir.RuntimeNode;
import lombok.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import sun.security.util.Password;
import java.util.Arrays;
import java.util.List;
//@RequestMapping可以放在元素上也可以放在方法上
//在类上面配置，@RequestMapping指在每一个方法前加该路径：http://localhost:8050/SpringMvc_war/msb/firstController.do
//,method = {RequestMethod.POST,RequestMethod.GET},params = {"password","username!=null"}
/*@RequestMapping("/mashibing")
* @RestController返回的是文字
* */
@RestController
public class FirstController {
@RequestMapping(value = "testMappering.do", method = RequestMethod.GET)
public String testMappering() {
System.out.println("RequestMapping收到访问");
return "first";
}
@RequestMapping("/firstController.do")
public String firstController() {
System.out.println("this is firstController");
//当return路径前加上/则路径从webapp开始执行，进行路径配置
return "first";
}
/*@RequestMapping( value = "/secondController.do",params = "password")*/
@RequestMapping("/secondController/{username}/{password}")
/*public String secondController(@RequestParam(value = "username") String username,@RequestParam(value = "password") String password){*/
public String secondController(@PathVariable("username") String username, @PathVariable("password") String password) {
System.out.println("this is firstController");
System.out.println("username:" + username);
System.out.println("password:" + password);
//当return路径前加上/则路径从webapp开始执行，进行路径配置
return "first";
}
//@RequestMapping("/threadController.do")这里的/可有可无
@RequestMapping(value = "/threadController.do" ,method = RequestMethod.GET)
public String threadController(ListArrays arrays ) {
/*System.out.println(Arrays.toString(persion.getHobby()));*/
System.out.println(arrays.getPets());
System.out.println(arrays.getPersions());
return "执行成功";
}
}
不同方式获取前端资源
//当没有实体类时RequestParam这个注解获取用户输入的密码
/*public String secondRequestParam(@RequestParam(value = "username") String username,@RequestParam(value = "password") String password){*/
