Java调用Python返回乱码问题解决

python代码如下

#coding:utf-8def keywordsRouter(keywords):      str = keywords+"这里是中文";    print("py=="+str);    return str;

java代码如下

Properties props = new Properties();//      props.put("python.home","path to the Lib folder");        props.put("python.console.encoding", "UTF-8"); // Used to prevent: console: Failed to install '': java.nio.charset.UnsupportedCharsetException: cp0.        props.put("python.security.respectJavaAccessibility", "false"); //don't respect java accessibility, so that we can access protected members on subclasses        props.put("python.import.site","false");        Properties preprops = System.getProperties();        PythonInterpreter.initialize(preprops, props, new String[0]);        PythonInterpreter interp = new PythonInterpreter();        String ret = "";        String pyfilePath = ".py文件的路径";        interp.execfile(pyfilePath);          PyFunction func = (PyFunction)interp.get("keywordsRouter",PyFunction.class);          PyObject pyobj = func.__call__(new PyString("传给keywordsRouter方法的参数"));          ret = pyobj.toString();//这里ret可能会乱码        String newStr = new String(ret.getBytes("iso8859-1"), "utf-8");  //通过new String(ret.getBytes("iso8859-1"), "utf-8")转一下就好了        System.out.println("anwser= " +newStr);  //newStr就不会乱码了        return newStr;
