这周一直在研究SpringMVC+Mybatis,有些心得,记录一下。

Ⅰ:建maven遇到的问题。

  1.1 新建maven时选中【Create a simple project】这样,后面【Packaging】选项有【war/pom/jar】可供选择。

  1.2 新建maven时没有web.xml文件,会报错方法一是从别的项目copy过来一份

    方法二:【Project Facets】取消【Dynamic web Module】并且将【Java】选项调到1.6以上,选【OK】

        重新选中【Project Facts】中【Dynamic web Module】,在下面有一个【Futher Configuration aviable】

        点击后,选中【Generate web.xml deployment】就会自动生成web.xml

        同时将WebContent换成-》src/main/webapp

        最后确认【Deployment Assembly】中 src/main/webapp 后为“/”项目的根目录

  1.3 在maven里使用【${spring.version}】,因为在上边【Properties】属性里,定义了全局变量。

        <properties>
           <spring.version>4.0.2.RELEASE</spring.version>
         </properties>

  1.4 使用了build插件的一个理解:没有加入这个声明时,是按照jdk1.3来编译的

      参考:http://www.infoq.com/cn/news/2011/04/xxb-maven-7-plugin

      <build> 
          <plugins> 
              <plugin> 
                  <groupId>org.apache.maven.plugins</groupId> 
                  <artifactId>maven-compiler-plugin</artifactId> 
                  <version>3.3</version> 
                  <configuration> 
                      <!-- 指定source和target的版本 -->                
                      <source>1.8</source>  =<source>${jdk.version}</source>
                      <target>1.8</target>   =<targer>${jdk.version}</targer>
                  </configuration> 
              </plugin> 
          </plugins> 
      </build>

Ⅱ:建spring工程需要的jar包
