Maven

第32集讲安装

Maven文件导入方式

先把对应文件夹拖到资源管理器

然后再让idea识别出这个是maven，记得通过pom.xml打开

依赖配置

Maven Repository: Search/Browse/Explore

排除依赖

命令行传参调用mvn时，要先配置MAVEN_HOME及其path，且同时要使得jdk匹配

测试

Junit

先导入，在pom.xml中

<dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter</artifactId>
        <version>5.9.1</version>
        <scope>test</scope>
    </dependency>
</dependencies>

package com.itheima;

import org.junit.jupiter.api.Test;

import java.time.LocalDate;

/**
 * 测试类
 */
public class UserServiceTest {
    @Test
    public void testGetAge(){
        UserService userService = new UserService();
        Integer age = userService.getAge("100000200010011011");
        System.out.println(age);
    }
}

断言机制（maven版）

package com.itheima;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;

import java.time.LocalDate;

/**
 * 测试类
 */
public class UserServiceTest {
    @Test
    public void testGetAge(){
        UserService userService = new UserService();
        Integer age = userService.getAge("100000200010011011");
        System.out.println(age);
    }

    @Test
    public void testGetGender(){
        UserService userService = new UserService();
        String gender = userService.getGender("100000200010011011");
        System.out.println(gender);
    }

    /**
     * 基于断言
     */
    @Test
    public void testGetGenderwithAssert(){
        UserService userService = new UserService();
        String gender = userService.getGender("100000200010011011");
        Assertions.assertEquals("男", gender,"男女颠倒");
        System.out.println(gender);
    }

    @Test
    public void testGetGenderwithAssert2(){
        UserService userService = new UserService();
        //断言
        Assertions.assertThrows(IllegalArgumentException.class, ()->{
            userService.getGender("null");
        });
    }
}

跳过该测试周期

C:\Users\Lenovo.m2\repository\org\springframework\spring-context\6.1.4

直接找到maven的本地仓库，cmd调用命令行，

C:\Users\Lenovo.m2\repository>del /s *.lastUpdated

仓库里面有一个del.bat格式的文件，直接双击运行脚本就可以删除

后端

Spring

package com.itheima;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController//表示当前类是一个请求处理类
public class HelloController {
    @RequestMapping("/hello")//标识请求路径
    public String hello(String name){
        System.out.println("name："+name);
        return "Hello"+name+"~";
    }
}

aliyun里面会默认给你一个demo包，调用前得先删掉这个包

https://docs.spring.io/spring-boot/docs/3.1.3/reference/htmlsingle/#using.build-systems.starters

HTTP协议

package com.itheima;

import jakarta.servlet.http.HttpServletRequest;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class RequestController {
    @RequestMapping("/request")
    public String request(HttpServletRequest request){
        //1.获取请求方式
        String method = request.getMethod();//GET还是POST
        System.out.println("请求方式："+method);
        //2.获取请求url地址
        String url = request.getRequestURL().toString();
        System.out.println("完整的URL地址："+url);
        String uri = request.getRequestURI();
        System.out.println("完整的URI地址："+uri);
        //3.获取请求协议
        String protocol = request.getProtocol();
        System.out.println("请求协议："+protocol);
        //4.获取请求参数name
        String name = request.getParameter("name");
        String age = request.getParameter("age");
        System.out.println(name);
        System.out.println(age);
        //5.获取请求头-Accept
        String accept = request.getHeader("Accept");
        System.out.println("Accept："+accept);

        return "OK";
    }
}
