Java怎么调用python

添加依赖

<dependency>
  <groupId>org.python</groupId>
  <artifactId>jython-slim</artifactId>
  <version>2.7.3</version>
</dependency>

示例代码

java中运行python

mport org.python.util.PythonInterpreter;

public class JythonHelloWorld {
  public static void main(String[] args) {
    try(PythonInterpreter pyInterp = new PythonInterpreter()) {
      pyInterp.exec("print('Hello Python World!')");
    }
  }
}

python中运行java

from java.lang import System # Java import

print('Running on Java version: ' + System.getProperty('java.version'))
print('Unix time from Java: ' + str(System.currentTimeMillis()))
