目录

更换日期格式

创建SpringMVC项目

 目录

补全目录结构 ：添加java项结构

导入jar包

添加tomcat运行快捷键

创建配置类 SpringMvcConfig.class

创建Controller类

使用配置类ServletConfig替换web.xml

日期类型比较特殊，因为对于日期的格式有N多中输入方式，比如:

• 2088-08-18

• 2088/08/18

• 08/18/2088

更换日期格式

携带时间的日期

添加tomcat运行快捷键

创建配置类 SpringMvcConfig.class

package com.itheima.config;
 
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
 
@Configuration
@ComponentScan("com.itheima.controller")
@EnableWebMvc
public class SpringmvcConfig {
}

创建Controller类

package com.itheima.controller;
 
import com.itheima.domain.User1;
import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
 
import java.util.Arrays;
import java.util.Date;
import java.util.List;
 
//@Controller：Springmvc的bean标志
@Controller
//@RequestMapping("/user")
public class UserController {
    @RequestMapping("/save")
    @ResponseBody
    public String save(){
        System.out.println("郭浩康第一个Sprintmvc项目创建成功");
        return "{spring1save()...}";
    }
    @RequestMapping("/delete")
    @ResponseBody
    public String delete(){
        System.out.println("");
        return "{detete删除运行成功}";
    }
    //普通参数
    @RequestMapping("/kk")
    @ResponseBody
    public String kk(String name, @RequestParam("age1") int age){
        System.out.println("收到参数:"+name);
        System.out.println("收到参数:"+age);
        return "{kk成功}";
    }
    //POJO参数：请求参数与形参对象中的属性对应即可完成参数传递
    @RequestMapping("/kk1")
    @ResponseBody
    public String pojoParam(User1 user){
        System.out.println("pojo参数传递 user ==> "+user);
        return "{'module':'pojo param'}";
    }
    //数组参数：同名请求参数可以直接映射到对应名称的形参数组对象中
    @RequestMapping("/kk2")
    @ResponseBody
    public String arrayParam(String[] likes){
        System.out.println("数组参数传递 likes ==> "+ Arrays.toString(likes));
        return "{'module':'array param'}";
    }
    //集合参数：同名请求参数可以使用@RequestParam注解映射到对应名称的集合对象中作为数据
    @RequestMapping("/kk3")
    @ResponseBody
    public String listParam(@RequestParam  List likes){
        System.out.println("集合参数传递 likes ==> "+ likes);
        return "{'module':'list param'}";
    }
    //使用@RequestBody注解将外部传递的json数组数据映射到形参的集合对象中作为数据
    @RequestMapping("/kk4")
    @ResponseBody
    public String listParamForJson(@RequestBody List likes){
        System.out.println("list common(json)参数传递 list ==> "+likes);
        return "{'module':'list common for json param'}";
    }
    @RequestMapping("/kk5")
    @ResponseBody
    public String dataParam(Date date,@DateTimeFormat(pattern = "yyyyy-mm-dd") Date date1){
    System.out.println("参数传递 date ==> "+date);
        System.out.println("参数传递 date1 ==> "+date1);
    return "{'module':'data param'}";
}
}

使用配置类ServletConfig替换web.xml

将web.xml删除，换成ServletContainersInitConfig

package com.itheima.config;
 
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.support.AbstractDispatcherServletInitializer;
 
public class ServletConfig extends AbstractDispatcherServletInitializer {
    //加载Springmvc容器
    @Override
    protected WebApplicationContext createServletApplicationContext() {
        AnnotationConfigWebApplicationContext ctx=new AnnotationConfigWebApplicationContext();
        ctx.register(SpringmvcConfig.class);
        return ctx;
    }
//设置请求处理
    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
//加载Spring容器
    @Override
    protected WebApplicationContext createRootApplicationContext() {
        return null;
    }
}

运行结果
