杂谈maven工程实践（3）

1、常见应用

maven工程中，主要操作的是pom.xml配置和java开发

java开发：代码&配置文件

pom.xml：管理maven功臣资源、依赖、插件等信息

 

 

2、资源管理

包括：jar包的资源管理、工程之家女的关系管理，常用信息的配置管理

 

资源定义

案例：开发mybatis的测试

定义：需要的jar包

资源来源：http://mvnrepository.com

 

 

资源的依赖

 

 

测试使用mybatis进行查询

 

 

mybatisconfig,xml

　　

db.propertis

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/users
jdbc.username=root
jdbc.password=1234

　　

UserMapper.xml

"1.0" encoding="UTF-8" ?>
DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
namespace="test">
     
     <select id="select" parameterType="int"  resultType="com.pojo.User">
           select * from user where id = #{id}
     select>
   

 

 

User.java

package com.pojo;

public class User {     

private int id;    
private String name;     

public int getId() {           
　　return id;     
}     

public void setId(int id) {           
　　this.id = id;     
}     

public String getName() {           
　　return name;     
}     

public void setName(String name) {           
　　this.name = name;     
}    
public User() {    
 }    
public User(int id, String name) {           
super();           
this.id = id;          
this.name = name;   
 }     
}

 

 

tests.java

public class tests {
     
     @Test
     public void testss() throws IOException{
           
           //配置文件的select
        String resource = "mybatisconfig.xml";
        //得到配置文件流
        InputStream inputStream =  Resources.getResourceAsStream(resource);
        
        //创建会话工程
        SqlSessionFactory sessionFactory = new  SqlSessionFactoryBuilder().build(inputStream);
  
        //通过工程得到Session
        SqlSession session = sessionFactory.openSession();
        
        //通过SqlSession操作数据库
        //session.selectOne(arg0, arg1)
        User user = session.selectOne("test.select", 2);
        System.out.println(user);
        
        session.close();
           
     }
}

 

 

 

 

3、本地安装

 

 

右键工程--》run as --》maven install

 

 

测试启动

 

 

服务启动

 

 

测试springmvc的使用进行启动tomcat

事务管理加载tx

使用tomcat

         org.apache.tomcat.maven
            tomcat7-maven-plugin
            2.2     
        
        
     
     
     
     
           
              org.apache.tomcat.maven
                 tomcat7-maven-plugin
                    
                       /
                       8081
                       tomcat7
                    
                     
            
     

 

 

 

 

TestController.java

package com.controller;

public class TestController {

    @RequestMapping("/test")
    public String test(){

   maven中的springmvc测试！！！
  

 

 

 

 

 

 

 

 

tomcat:deploy   --部署一个web war包

tomcat:reload   --重新加载web war包

tomcat:start    --启动tomcat

tomcat:stop    --停止tomcat

tomcat:undeploy--停止一个war包

tomcat:run  启动嵌入式tomcat ，并运行当前项目
