AnnotationTransactionAttributeSource is only available on Java 1.5 and higher

如果编写maven项目出现以下错误，但是跟jdk配置和Tomcat无关，可能与dubbo配置有关，则可通过修改pom文件中配置，进行改正。

可以修改pom文件：

<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>${com.alibaba.dubbo.version}</version>
<exclusions>
<exclusion>
<artifactId>spring</artifactId>
<groupId>org.springframework</groupId>
</exclusion>
</exclusions>
</dependency>
