java访问报错：
第一次的时候还能正常使用，编译之后报错
jfinal Can not get javax.tools.JavaCompiler, check whether "tools.jar" is in the environment variable CLASSPATH
原因：

添加了注入Proxy 动态代理，需要：在main添加代码：
public void configConstant(Constants me) {
// 4.6 之前的版本的配置方式: me.setProxyFactory(new CglibProxyFactory());
me.setToCglibProxyFactory(); // 4.6 版本新增配置方式
}
pom.xml添加依赖
