When I was in a XXL - time job tasks dynamically generated using aop method instance objects, but will quote connection timeout, don't know what went wrong there

This is my code to the

 
@ Around (routeMongoDB "()") 
Public Object routeMongoDB (ProceedingJoinPoint joinPoint) {
The Object result=null; 
Object [] args=joinPoint. GetArgs (); 
String db=String. The valueOf (args [0]). 
The Object o=joinPoint. GetTarget (); 
Field [] fields=o.g etClass () getDeclaredFields (); 
MultiMongoTemplate mongoTemplate=null; 
Try {
For (Field Field: fields) {
Field. SetAccessible (true); 
Object fieldObject=field. The get (o); 
The Class fieldclass=fieldObject. GetClass (); 
//find the Template variable 
If (fieldclass==MongoTemplate. Class | | fieldclass==MultiMongoTemplate. Class) {
//find the corresponding MongFactory 
SimpleMongoClientDbFactory SimpleMongoClientDbFactory=(SimpleMongoClientDbFactory) templateMuliteMap. Get (db); 
//instantiate 
If (simpleMongoClientDbFactory==null) {
//based on dbname query data corresponding address 
This. Uri=testMongoUriDao. FindByAppId (db). GetUri (); 
//replace data 
SimpleMongoClientDbFactory=new simpleMongoClientDbFactory (this) uri) replace (" # ", db)); 
TemplateMuliteMap. Put (db, simpleMongoClientDbFactory); 
} 
//if the first time, the assignment into custom MongoTemplate subclass 
If (fieldclass==MongoTemplate. Class) {
MongoTemplate=new MultiMongoTemplate (simpleMongoClientDbFactory); 
} else if (fieldclass==MultiMongoTemplate. Class) {
MongoTemplate=(MultiMongoTemplate fieldObject); 
} 
//set MongoFactory 
MongoTemplate. SetMongoDbFactory (simpleMongoClientDbFactory); 
//to assignment 
Field. The set (o, mongoTemplate); 
break; 
} 
} 
Try {
Result=joinPoint. Proceed (); 
//clean the ThreadLocal variable 
MongoTemplate. RemoveMongoDbFactory (); 
{} the catch (Throwable t) 
Logger. The error (" ", t); 
} 
} the catch (Exception e) {
Logger. The error (" ", e); 
} 

return result; 
}
