thrift开发环境的搭建

1.http://thrift.apache.org/docs/
2.http://thrift.apache.org/docs/BuildingFromSource
3.http://thrift.apache.org/docs/install/
4.http://thrift.apache.org/docs/install/centos

在纯净的CentOS7.3的环境中,应该如下操作。
sudo yum -y groupinstall “Development Tools”
sudo yum -y zlib-devel openssl-devel ant
安装libevent-2.0.22-stable.tar.gz
安装boost_1_53_0.tar.gz
安装thrift-0.9.3.tar.gz

JAVA和antoconf、automake、bison是系统自带的,只需要增加ant的安装。

Spring-aop的局限性

采用@Aspect、@Before、@After、@Around、@Pointcut、这类注解实现的AOP,存在一些局限性
1.只能用在spring容器管理的类上面进行aop,如@Controller、@Service、@Component、@Reprository等。
2.切入点只能在方法级别。
3.只有被代理的外部类的方法才能被拦截,而内部类调用的函数,才不行。
主要原因是其命名用CGlib的AOP的Proxy实现的。
JDK动态代理是模拟接口实现的方式,cglib是模拟子类继承的方式

javaagent模式的AOP方式。

在catalina.bat中,的首行配置如下:

rem 在IDEAJ2016.3.6版本中,调试模式下,会卡死,并无法初始化MVC容器。
rem set JAVA_OPTS="-javaagent:C:\apache-tomcat-8.5.11\aspectjweaver-1.8.2.jar"
rem 在IDEAJ2016.3.6版本中,调试模式下,会卡死,并无法初始化MVC容器。
rem set JAVA_OPTS=-javaagent:"C:\apache-tomcat-8.5.11\aspectjweaver-1.8.2.jar"
rem 以下方式,是目前验证可行的方法。
set JAVA_OPTS=%JAVA_OPTS% -javaagent:"C:\apache-tomcat-8.5.11\aspectjweaver-1.8.2.jar"

可行的如下:

不可行的如下:
