Jfianl aop 和 利用aop 自己定义一个Service异常

package cn.necsthz.cjzbapi.exception;

public class ServiceException extends RuntimeException {

private static final long serialVersionUID = -717382329506444034L;

private int code;
private String errmsg;

public ServiceException(int code, String errmsg) {
this.code = code;
this.errmsg = errmsg;
}

public int getCode() {
return code;
}

public String getErrmsg() {
return errmsg;
}
}

=========================================================
@Before({ POST.class, Tx.class, DecryptParamsInterceptor.class })

========================================================
DecryptParamsInterceptor.class ：

} catch (ServiceException ex) {
JsonResult result = new JsonResult();
result.code = ex.getCode();
result.errmsg = ex.getErrmsg();
ctl.renderJson(result);
ctl.logger.error(ex.getErrmsg());
throw new NestedTransactionHelpException(ex.getErrmsg());

=================================================================
Tx.class：

try {
conn = config.getConnection();
autoCommit = conn.getAutoCommit();
config.setThreadLocalConnection(conn);
conn.setTransactionIsolation(getTransactionLevel(config));    // conn.setTransactionIsolation(transactionLevel);
conn.setAutoCommit(false);
inv.invoke();
conn.commit();
} catch (NestedTransactionHelpException e) {
if (conn != null) try {conn.rollback();} catch (Exception e1) {LogKit.error(e1.getMessage(), e1);}
LogKit.logNothing(e);
