spring5x-base-目录.png
此模块是基础模块，其它模块都是以此模块扩展
Spring5x-base:是一个非常干净的spring5.x+springMVC架构
Spring5x-base的作用：
- 可以直接拷贝这个模块，改名成其它模块名称
推荐-接口调试：
- 浏览器调用调试接口
- Postman 工具调用接口调试(极力建议)
- swagger Api 调试接口(推荐)
Spring5x-base 搭建过程：
功能：
- 单纯的 spring+springmvc 框架
- 版本spring 5.x
项目结构：特别简单的基础框架，往后的spring xml配置方式都是以此框架的为基础。

1、pom.xml 引入依赖

2、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">
<!-- 开启注解包扫描-->
<context:component-scan base-package="com.zja.*"/>
<!--使用默认的 Servlet 来响应静态文件 -->
<mvc:default-servlet-handler/>
<!-- 开启springMVC 注解驱动 -->
<mvc:annotation-driven>
<mvc:message-converters register-defaults="false">
<!-- 将StringHttpMessageConverter的默认编码设为UTF-8 ，解决返回给前端中文乱码-->
<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，这个文件里没有内容 -->
<context:property-placeholder
location="classpath*:application.properties" />
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
id="internalResourceViewResolver">
<!-- 前缀 ：/WEB-INF/jsp/和/WEB-INF/html/-->
<property name="prefix" value="/WEB-INF/jsp/"/>
<!-- 后缀 ：.jsp和.html-->
<property name="suffix" value=".jsp"/>
</bean>
</beans>
3、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 接口测试
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页面
return "hello";
}
@GetMapping("/hello2")
@ResponseBody
public String hello2(){
//返回字符串
return "hello2 字符串";
}
}
5、测试-页面访问
- 访问：http://localhost:8080/spring5x-base/hello
- 效果：hello.jsp 页面 或 hello.html 页面
数据访问
- 访问：http://localhost:8080/spring5x-base/hello2
- 效果：hello2 字符串
基础搭建已经可以结束！！！
