1、使用spring framework 5.2.1 REALSE
2、創建maven 工程
點擊完成，這個maven工程就是搭建OK了。
---- 本地安裝tomcat，我使用的版本是tomcat8.5
添加後，會出現這個。
引入springMVC，pom.xml
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.2.1.RELEASE</version>
</dependency>
---需要配置的目錄如下：
web.xml 是默認的文件在裏面配置如下：
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>Archetype Created Web Application</display-name>
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
servlet 的 name 是 springmvc 要和上面截圖的springmvc-servlet.xml 前綴一樣，不然在啓動時會遇到讀取不到的問題。
<?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"

http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 搜索spring控件 -->
<context:component-scan base-package="com.fandong.weapon.controller"></context:component-scan>
<!-- 開啓springMVC的註解驅動，使得url可以映射到對應的controller -->
<mvc:annotation-driven />
<!-- 視圖頁面配置 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>/WEB-INF/jsp/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
</beans>
設定component-scan 掃描包的，
---HelloController
package com.fandong.weapon.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class HelloController {
@RequestMapping(value="/hello",method=RequestMethod.GET)
public String printHello(ModelMap model) {
model.addAttribute("message","你好的，小子");
System.out.println("-------------------------************** hmemee");
return "hello";
}
}
設定jsp頁面：
這個表，
<%@ page language="java" isELIgnored="false" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<span>${message}</span>
</body>
</html>
注意 isELIgnored="false" 否則到時message 會無法序列化。
----本地啓動。
---搭建tomcat 服務器。
下載tomcat8.5 解壓：
啓動：
cd /tomcat/bin
./startup.sh
---修改tomcat文件：
[root@hadoop01 conf]# ls
Catalina catalina.policy catalina.properties context.xml jaspic-providers.xml jaspic-providers.xsd logging.properties server.xml tomcat-users.xml tomcat-users.xsd web.xml
[root@hadoop01 conf]# cat tomcat-users.xml
<?xml version="1.0" encoding="UTF-8"?>

<tomcat-users xmlns="http://tomcat.apache.org/xml"

<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<user username="tomcat" password="tomcat" roles="manager-gui,manager-script"/>
</tomcat-users>
[root@hadoop01 conf]#
設定用戶、賬戶和密碼。
--在修改可以遠程訪問：
[root@hadoop01 manager]# pwd
/opt/tomcat/tomcat-8.5.50/webapps/manager
[root@hadoop01 manager]# cd META-INF/
[root@hadoop01 META-INF]# ls
context.xml

----在pom.xml 配置tomcat-maven 插件
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<!-- 這裏配置端口號和訪問路徑 -->
<path>/</path>
<url>http://hadoop01.fandong.com:8080/manager/text</url>
<username>tomcat</username>
<password>tomcat</password>
<update>true</update>
</configuration>
</plugin>
這裏一定是<update>true</update> 不然更新會出錯的。
