The code for loading the configuration file is as follows:

ApplicationContext context = new ClassPathXmlApplicationContext ("spring/spring-datasource-mogon.xml ");

Previously, I encountered a similar problem when writing a unit test. There was no problem in querying, checking code, and loading methods, that is, the file could not be found in an error, and I was puzzled, I always thought it was related to the environment.

When debugging mongo today, I finally found the problem.

If a problem occurs: if the project is updated or refreshed, the above error is reported;

Solution:

1. Create a configuration file with the same content and different names; for example, change the name of the configuration file/spring-datasource-mogon.xml to/spring-datasource-mogon-1.xm

2. modify the code to load the configuration file: ApplicationContext context = new ClassPathXmlApplicationContext ("spring/spring-datasource-mogon-1.xml ");

3. debug and find that there is no such problem.

Summary:

1. After the project is updated, the unit test loaded project will also be refreshed. when the project is refreshed, the configuration file will be deleted from the project environment.

2. Modifying the name is equivalent to adding a new file, which will be synchronized in the project environment.

3. Therefore, the program can be found when loading new files, but the old one cannot be found.

4. The path of the configuration file loaded by the unit test is not found. If yes, you can directly add the old configuration file to it.

5. Legacy questions: when asked what refresh project, all configuration files will be cleared; how can this be avoided?

6. What is the difference between the editing and storage path of the project and the project running environment path.
