如何使用spring的注解驱动aspectj模式

1、首先在spring的配置文件中添加<tx:annotation-driven transaction-manager="transactionManager" mode="aspectj"/>mode设置为aspectj模式

2、jvm参数里添加-javaagent:~aspectjweaver-1.8.1.jar

3、如果是tomcat下，也可以添加到catalina.sh中，set JAVA_OPTS中

4、-javaagent参数添加完成时候，启动服务就可以正常使用aspectj模式了上面说的方法是类加载器织入（Load Time Weaving,LTW），下面再介绍另外一种方法，编译时织入

5、在pom.xml文件中加入aspectj-maven-plugin插件配置<plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>aspectj-maven-plugin</artifactId> <version>1.9</version> <configuration> <showWeaveInfo>true</showWeaveInfo> <aspectLibraries> <aspectLibrary> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> </aspectLibrary> </aspectLibraries> <source>${java.version}</source> <target>${java.version}</target> <complianceLevel>${java.version}</complianceLevel> </configuration> <executions> <execution> <goals> <goal>compile</goal> <goal>test-compile</goal> </goals> </execution> </executions></plugin>

6、这几个配置要加上<source>${java.version}</source><target>${j锾攒揉敫ava.version}</target><complianceLevel>${java.version}</complianceLevel>否则可能会报以下错误[ERROR] Syntax error, annotations are only available if source level is 1.5 or greater E:\work\datai\code_study\study-master\study-spring-transaction\src\main\java\cn\sw\study\web\controller\UserController.java:12@Controller^^^^^^^^^^[ERROR] Syntax error, annotations are only available if source level is 1.5 or greater E:\work\datai\code_study\study-master\study-spring-transaction\src\main\java\cn\sw\study\web\controller\UserController.java:13@RequestMapping("/user")[ERROR] Missing message: configure.incompatibleComplianceForSource in: org.aspectj.ajdt.ajc.messages <unknown source file>:<no line information>[ERROR] no sources specified <unknown source file>:<no line information>

7、添加完成之后，maven进行编译，如果出现java:0::0 can't determine annotations of missing type javax.persistence.Entity错误，

8、则需要添加persistence-api依赖<dependency> <groupId>javax.persistence</groupId> <artifactId>persistence-api</artifactId> <version>1.0</version> <scope>provided</scope></dependency>

9、编译完成没有错误之后，这个时候不用加-javaagent，再次启动项目，一样可以完成事务织入
