The DAE service executeUpdate interface is taken as an example to introduce a specific interface implementation scheme:
analyzing the length of the TransID field in the interface message, reading the TransID in the stream according to the length of the field, and capturing various abnormal information acquired in the analyzing process. And returning some error code (such as 0602) of the client after the exception occurs. Analyzing the length of the PSID field in the interface message, reading the PSID in the stream according to the length of the field, and capturing various abnormal information acquired in the analyzing process. And returning some error code (such as 0603) of the client after the exception occurs. And acquiring a real preparestate object according to the psID + transID in the message, executing executeUpdate operation by using the preparestate object, capturing an exception, printing exception information, and returning a certain error code (such as 0601) which fails to execute updating.
And executing normal assembly message return results, analyzing the length of the transID field in the interface message, reading the transID in the stream according to the length of the byte, capturing various abnormal information acquired in the analyzing process, and returning a client error code 0602 after abnormality occurs. Reading and executing the compression mark in the header of the update message and caching the record, wherein the execution of the update compression mark is 1 message compression, and the message needs to be decompressed. And circularly acquiring the corresponding binding variable according to the number of the binding variables in the execution updating message, and executing the updating operation according to the acquired binding field degree and the remaining binding variable values. Analyzing, executing and updating the type of the binding variable and the real value or the anti-sequence of the binding variable according to the separator to obtain a value, checking the execution updating variable according to the obtained variable type, and returning an error code after checking errors. And carrying out legal verification on the variable type in the verification execution updating and analysis process, wherein the variable is an object and is required to be subjected to deserialization operation according to the execution updating variable type. Checking the length of the parameters of the storage process in the updating execution operation, carrying out validity check according to the number length of the registration parameters, and carrying out cyclic processing according to the number of the registration parameters for executing the updating storage process.
2. And (3) modifying Java Database connection (JDBC) of the client.
2.1, the client provides the implementation of a Driver class.
Providing a Driver method for realizing, providing a connect realizing method, a transparent transmission jdbc interface method, providing a createConnection method, a jdbc interface method, providing an acceptsrol method, a transparent transmission jdbc interface method, providing a getPropertyInfo method and a transparent transmission jdbc interface method.

The method comprises the following steps: the client comprises a client prepareStateinterface, a client prepareCall interface, a client executeQuery interface, a client QueryNext interface, a client executeUpdate interface, a client commit interface, a client rollback interface, a client CLOSE interface and a client GETPS interface.
The concrete implementation scheme is introduced by taking a commit interface called by a client as an example:
acquiring a corresponding servername according to a connection object transmitted by a client, acquiring a corresponding DAE service connection according to the servername, acquiring a transit id of a corresponding DAE according to the connection object + the servername, and acquiring an sql, a binding variable value and a parameter value of all extraordinary operations of the transaction according to the transit id. According to the configured sql, the sql of the redo is needed to be written into the transition _ log table, and the prefix (transfId, servername, sql, bindvar) of DAE is called. The return result psId of preparentatement is resolved, execute (transit ID, psId) of DAE is called, and commit (transit Id) is called as the return result of DAE. And if the result is overtime or abnormal processing is carried out when abnormal conditions are returned, calling a prepareStatement interface to inquire about the transitions _ log table and acquiring whether the corresponding transID is successfully submitted. And (5) directly returning the success of the client after the success of the submission. If the operation is not inquired, judging that the operation sql is the redo sql, needing to newly create a transaction ID, recalling the DAE service of the previous premarstation statement according to the new transID, and calling (transID, psid) of execute of the DAE to mark that the transaction is not executed successfully. And returning the execution failure of the client.
3. The adaptation and modification of the related JAVA application process (taking a user data refreshing process as an example) are realized.
The user data refreshing process uses a jdbc interface to connect data, a native jdbc interface is mainly used directly, a dbutil interface is used, and a groovy SQL interface which partially uses groovy needs to be adapted. The method comprises the steps of adapting a preparsestatus interface of a jdbc of a refreshing process, adapting a preparally interface of the jdbc of the refreshing process, adapting an executequery interface of the jdbc of the refreshing process, adapting an execlute interface of the jdbc of the refreshing process, adapting a commit interface of the jdbc of the refreshing process, adapting a rollback interface of the jdbc of the refreshing process, adapting an execlute interface of a dbutil of a cbs-core public packet, adapting a queryOne interface of a dbutil of a cbs-core public packet, adapting a query interface of a dbutil of a cbs-core public packet, adapting a secondary login interface JavaSecondonLogon, and driving to use a new client ngjdbc.
The embodiment innovatively designs a using method for solving the problems that when a Java application program in the BOSS billing and accounting system of the current network accesses a database, the system performance is reduced due to excessive connection numbers caused by establishing independent connections, and when the database is abnormal, the database is switched to cause the inconvenience of operation and maintenance caused by the need of manually processing data connection strings, and the key points of the method are as follows:
