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

Ⅲ:切换workspace时,要检查setting.xml文件是否是自己需要的。
