1. The libTest.so file is placed in the java.library.path directory of the linux system (System.getProperty( "java.library.pah") can be obtained ) 2. Create a new java project that loads soload static { String soPath="Test"; System.loadLibrary(soPath); } Note that there is no lib prefix and so suffix here publicnativeintTest(int x,int y); Package the file as a jar package soload.jar , and then include the jar package into the maven -structured web project <dependency> <groupId>com.baidu.java</groupId><!--自定义 --> <artifactId>soload</artifactId><!--自定义 --> < version > 1.0 </ version > <!--customize--> < scope > system </ scope > <!--system, similar to provided, after you need to explicitly provide the dependent jar, Maven will not look it up in the Repository --> < systemPath > ${ basedir }/ lib /soload.jar </ systemPath > <!-- under the lib folder under the project root directory --> </dependency> There is no need to include the jar package into the war package here 1. Upload the soload.jar package to the ${tomcat}/server/lib directory , create it if there is no server/lib directory , and then modify server.loader=${catalina. base}/server/classes,${catalina.base}/server/lib/*.jar shared.loader=${catalina.base}/server/classes,${catalina.base}/server/lib/*.jar Note: server.loader and shared.loader are the same Indicates that the jar package in the ${tomcat}/server/lib directory will be automatically loaded after tomcat is started 2. 将war包上传到webapp中，然后启动tomcat，当再次需要发布war项目时(没有修改soload.jar)直接将war包上传到webapp中，不需要重启tomcat |
