SSM（SpringMVC+Spring+Mybatis）

First, build SpringMVC

　　1, introduced in the spring-webmvc dependent project maven

        <!-- springmvc -->
      <dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-webmvc</artifactId>
          <version>5.1.8.RELEASE</version>
      </dependency>    

　　2, web.xml configuration file, add the following code in web.xml

<servlet>
      <servlet-name>HelloWeb</servlet-name>
      <servlet-class>
         org.springframework.web.servlet.DispatcherServlet
      </ The servlet-class > 
      <-! The springmvc core profile to modify the position of src / main / resources File -> 
      < the init-param > 
            < param-name > the contextConfigLocation </ param-name > 
            < param-value > CLASSPATH: springmvc.xml </ param-value > 
      </ the init-param > 
      < Load-ON-Startup > . 1 </ Load-ON-Startup > 
   </ the servlet > 
   < the servlet-Mapping > 
      < the servlet-name >HelloWeb</servlet-name>
      <url-pattern>/</url-pattern>
   </servlet-mapping>

 　　3, configuration springmvc core configuration file, create a file springmvc.xml in src / main / resources file

　　　　File names must web.xml file <param-value> classpath: springmvc.xml </ param-value> the same name

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
   http://www.springframework.org/schema/beans     
   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
   http://www.springframework.org/schema/context 
   http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <! - notes under scanning com.blb.controller -> 
    < context: Scan-Component Base-Package = "com.blb.controller"  />

    <!-- 视图解析器 -->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

　　4, write test classes

　　Creating com.blb.controller package in src / main / java file, create a class in the package TestController

package com.blb.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class TestController {
    
    // return to the browser 
    @ResponseBody
     // intercept address 
    @ RequestMapping ( "the Hello" )
     public String the Test () {
         return "the Hello world" ;
    }

}

　　5, maven configure tomcat and jdk

<build>
    <finalName>SSM_T</finalName>
    <plugins>  
        <!-- jdk配置 -->
        <plugin>  
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>  
            <version>3.1</version>  
            <configuration>  
                <source>1.8</source>  
                <target>1.8</target>  
            </configuration>  
        </plugin>
        
        <!-- 配置apache提供的tomcat插件 -->
        <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.2</version>
        </plugin>
     </plugins>  
  </build>

　　6, test, launch maven project

　　　　Access localhost: 8080 / project name / hello

　　　　Page appears hello world build the successful representation springmvc
