此模塊是基礎(chǔ)模塊，其它模塊都是以此模塊擴展
Spring5x-base:是一個非常干凈的spring5.x+springMVC架構(gòu)
Spring5x-base的作用：
- 可以直接拷貝這個模塊，改名成其它模塊名稱
推薦-接口調(diào)試：
- 瀏覽器調(diào)用調(diào)試接口
- Postman 工具調(diào)用接口調(diào)試(極力建議)
- swagger Api 調(diào)試接口(推薦)
Spring5x-base 搭建過程：
功能：
- 單純的 spring+springmvc 框架
- 版本spring 5.x
項目結(jié)構(gòu)：特別簡單的基礎(chǔ)框架，往后的spring xml配置方式都是以此框架的為基礎(chǔ)。

2边器、spring-mvc.xml 配置
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 開啟注解包掃描-->
<context:component-scan base-package="com.zja.*"/>
<!--使用默認的 Servlet 來響應(yīng)靜態(tài)文件 -->
<mvc:default-servlet-handler/>
<!-- 開啟springMVC 注解驅(qū)動 -->
<mvc:annotation-driven>
<mvc:message-converters register-defaults="false">
<!-- 將StringHttpMessageConverter的默認編碼設(shè)為UTF-8 ，解決返回給前端中文亂碼-->
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<constructor-arg value="UTF-8"/>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<!-- 增加application.properties文件托修，這個文件里沒有內(nèi)容 -->
<context:property-placeholder
location="classpath*:application.properties" />
<!-- 配置視圖解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
id="internalResourceViewResolver">
<!-- 前綴 ：/WEB-INF/jsp/和/WEB-INF/html/-->
<property name="prefix" value="/WEB-INF/jsp/"/>
<!-- 后綴 ：.jsp和.html-->
<property name="suffix" value=".jsp"/>
</bean>
</beans>
3忘巧、web.xml 配置
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<!--配置spring前端控制器-->
<servlet>
<servlet-name>springMvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:META-INF/spring/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
4、HelloController 接口測試
package com.zja.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
/**
* @author ZhengJa
* @description HelloController
* @data 2019/10/24
*/
@Controller
public class HelloController {
@GetMapping("/hello")
public String hello(){
//返回hello頁面
return "hello";
}
@GetMapping("/hello2")
@ResponseBody
public String hello2(){
//返回字符串
return "hello2 字符串";
}
}
5睦刃、測試-頁面訪問
- 訪問：http://localhost:8080/spring5x-base/hello
- 效果：hello.jsp 頁面 或 hello.html 頁面
數(shù)據(jù)訪問
- 訪問：http://localhost:8080/spring5x-base/hello2
- 效果：hello2 字符串
基礎(chǔ)搭建已經(jīng)可以結(jié)束Ｑ庾臁！涩拙！
