Configuration Dependency

The execution of Java programs—except for internally developed applications—typically relies on third-party open-source software. The Configuration Dependency described in this chapter involve installing the relevant packages and driver dependencies required for the transparent encryption/decryption runtime; this ensures that plugins can be loaded and invoked correctly, and prevents errors caused by missing components during application startup or data read/write operations.

Common Ways to Add Dependencies

  • Generally, place the bcprov-jdk18on-1.79.jar and encryption-proxy.jar files directly into the WEB-INF/lib directory of your web application; this is all that's needed.
  • If the third-party JAR files required by the program are located in a separate directory, extract the ZIP archive downloaded from the Downloading the Plugin, then copy the files bcprov-jdk18on-1.79.jar and encryption-proxy.jar to the third-party dependency directory of the business system service.Downloading the Plugin.
  • For a Spring Boot application where both the native code and its dependencies are contained within a single JAR file, you need to extract the ZIP archive downloaded from the Download Plugins section, then copy the two files — bcprov-jdk18on-1.79.jar and encryption-proxy.jar — into the BOOT-INF/lib directory of the JAR file.

Configuration Dependency – Spring Boot Application

  1. Extract the ZIP archive downloaded from the Downloading the Plugin and copy the two files into the same directory on your Windows host, e.g., D:\Application-Plugin Integration.
  2. Place the self-developed JAR file into the D:\Application-Plugin Integration directory. Right-click on the file, select Open With from the pop-up menu, and then choose WinRAR, as shown in Figure 1.

  3. The structure of the open self-developed package is shown in Figure 2.

  4. Double-click the BOOT-INF directory, then double-click the lib directory to view the dependency packages for the current in-house developed application, as shown in Figure 3.

  5. Click the left mouse button to extract the bcprov-jdk18on-1.79.jar file, which is located in the same directory; then drag the file to the WinRAR interface and release the left mouse button. In the pop-up Archive Name and Parameters dialog box, change the Compression Method to Store, and then click OK (as shown in Figure 4). Repeat the same procedure to add the encryption-proxy.jar file.
