記錄一下 自己遇到的異常以便以後查閱

 這個異常是由於 缺了  spring-context.jar

  可以對照一下是否缺了 spring的jar。我這邊把spring的jar全部引入了。

           <dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-expression</artifactId>
<version>4.1.3.Release</version>
</dependency>

  <dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.1.3.Release</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>4.1.3.Release</version>
</dependency>

  <dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.1.3.Release</version>
</dependency>

還可以切換到 專案所在目錄通過   mvn dependency:analyze命令來檢視 沒有引入的jar。

輸入命令後，查詢 user declared dependencies found:下面需要引入的jar .這時只要在 pom中加上這些jar就可以了。

不對的地方 還請留言
