在Spring Boot中加载.so文件,可以按照以下步骤进行操作:
将.so文件放置在项目的某个目录下,比如src/main/resources/native
目录。
在pom.xml
文件中导入org.springframework.boot:spring-boot-starter
依赖以及org.springframework.boot:spring-boot-maven-plugin
插件。
在src/main/java
目录下创建一个自定义的NativeLibraryLoader
类,用于加载.so文件。示例代码如下:
import org.springframework.stereotype.Component;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
@Component
public class NativeLibraryLoader {
public void loadLibrary(String libraryName) {
try {
File tempFile = File.createTempFile(libraryName, ".so");
tempFile.deleteOnExit();
try (InputStream is = getClass().getResourceAsStream("/native/" + libraryName + ".so");
FileOutputStream os = new FileOutputStream(tempFile)) {
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = is.read(buffer)) != -1) {
os.write(buffer, 0, bytesRead);
}
}
System.load(tempFile.getAbsolutePath());
} catch (IOException e) {
e.printStackTrace();
}
}
}
@Autowired
注入NativeLibraryLoader
对象,并调用loadLibrary
方法加载.so文件。示例代码如下:import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;
@Component
public class MyApplication implements CommandLineRunner {
@Autowired
private NativeLibraryLoader nativeLibraryLoader;
@Override
public void run(String... args) throws Exception {
nativeLibraryLoader.loadLibrary("myLibrary");
}
}
通过以上步骤,你就可以在Spring Boot中成功加载.so文件了。请根据实际情况修改libraryName
和.so文件的目录。
