  • Java 系列之spring学习--spring搭建(一)

    一、新建maven项目

    二、引入spring jar包

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
      <modelVersion>4.0.0</modelVersion>
      <groupId>wjxiaoqiao</groupId>
      <artifactId>wj</artifactId>
      <packaging>war</packaging>
      <version>0.0.1-SNAPSHOT</version>
      <name>wj Maven Webapp</name>
      <url>http://maven.apache.org</url>
      <dependencies>
      <!-- https://mvnrepository.com/artifact/org.springframework/spring-context -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>5.0.2.RELEASE</version>
    </dependency>
      
      <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>4.0.0</version>
        <scope>provided</scope>
    </dependency>
      
        <dependency>
          <groupId>junit</groupId>
          <artifactId>junit</artifactId>
          <version>3.8.1</version>
          <scope>test</scope>
        </dependency>
      </dependencies>
      <build>
        <finalName>wj</finalName>
      </build>
    </project>
    

    三、编写配置文件

    <?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"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/mvc 
           http://www.springframework.org/schema/mvc/spring-mvc.xsd 
           http://www.springframework.org/schema/context 
           http://www.springframework.org/schema/context/spring-context.xsd 
           http://www.springframework.org/schema/aop 
           http://www.springframework.org/schema/aop/spring-aop.xsd 
           http://www.springframework.org/schema/tx 
           http://www.springframework.org/schema/tx/spring-tx.xsd
           ">
       
        <bean id="test01" class="test.test01" /> 
    </beans>
    

    四、测试类

    package test;
    
    public class test01 {
    
    	public test01()
    	{
    		System.out.println("test01");
    		
    	}
    	public void prints()
    	{
    		
    		System.out.println("prints");
    	}
    }
    
    package test;
    
    import java.io.IOException;
    import java.io.PrintWriter;
    
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    public class aservlet extends HttpServlet {
    
    	public void doGet(HttpServletRequest request, HttpServletResponse response)
    			throws ServletException, IOException {
    
    		ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
    		test01 test01=(test01)context.getBean("test01");
    		test01.prints();
    	}
    
    }
    

    五、测试是否成功
