maven+spring+hibernate

1.配置文件

pom.xml

指定一个spring.version变量

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <spring.version>4.0.0.RELEASE</spring.version>
  </properties>

把spring+hibernate核心包引进

 1     <dependency>
 2         <groupId>org.springframework</groupId>
 3         <artifactId>spring-web</artifactId>
 4         <version>${spring.version}</version>
 5     </dependency>
 6     <dependency>
 7         <groupId>org.springframework</groupId>
 8         <artifactId>spring-orm</artifactId>
 9         <version>${spring.version}</version>
10     </dependency>
11     <dependency>
12         <groupId>org.hibernate</groupId>
13         <artifactId>hibernate-core</artifactId>
14         <version>3.6.10.Final</version>
15     </dependency>

还需要 web和数据库交互的需要

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>4.0.0.RELEASE</version>
    </dependency>
    <dependency>
      <groupId>org.codehaus.jackson</groupId>
      <artifactId>jackson-mapper-asl</artifactId>
      <version>1.9.13</version>
    </dependency>
    <dependency>
      <groupId>javassist</groupId>
      <artifactId>javassist</artifactId>
      <version>3.11.0.GA</version>
    </dependency>
    <dependency>
      <groupId>c3p0</groupId>
      <artifactId>c3p0</artifactId>
      <version>0.9.1.2</version>
    </dependency>
    <dependency>
      <groupId>com.mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>5.0.8</version>
      <classifier>bin</classifier>
    </dependency>
