Spring日记_02之搭建一个新项目

程序

表现层业务层持久层

从持久层开始写

总结如何搭建一个项目

1、新建一个Maven项目

2、可能新建之后会有错，右键Deployment Descriptor: note, 选择Generate Deployment Descriptor Stub

3、使用maven仓库导包

<dependencies>
      <dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-webmvc-portlet</artifactId>
          <version>3.2.8.RELEASE</version>
      </dependency>
      
      <dependency>
          <groupId>com.fasterxml.jackson.core</groupId>
          <artifactId>jackson-databind</artifactId>
          <version>2.8.5</version>
      </dependency>
      
     <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-core</artifactId>
      <version>2.8.5</version>
    </dependency>
    
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-annotations</artifactId>
      <version>2.8.5</version>
    </dependency>

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>3.2.8.RELEASE</version>
    </dependency>
    
    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis</artifactId>
      <version>3.4.0</version>
    </dependency>

    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis-spring</artifactId>
      <version>1.3.1</version>
    </dependency>

    <dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>5.1.38</version>
    </dependency>

    <dependency>
      <groupId>commons-dbcp</groupId>
      <artifactId>commons-dbcp</artifactId>
      <version>1.4</version>
    </dependency>

  </dependencies>

dependencies

3.1、查看一下下载的包

如果maven的包迟迟不下载，就右键项目，选择maven – UpdateProject

4、为项目指定tomcat运行环境

右键项目 – Properties – Targeted Runtimes

5.在下面server的tomcat服务器中添加项目

6 、在src/main/resources下添加两个文件夹

7 、 Spring配置文件

先将原项目的两个配置文件 spring-service.xml和 spring-mybatis.xml 复制过来

将spring-service.xml 改名为spring-web.xml,因为这样更合适一点

spring-mybatis.xml注意改一下文件里的包名，其他的关于mybatis的不用改

spring-web.xml如下：

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</beans>

spring-web.xml

spring-mybatis.xml如下：
