Java代码编译java文件到字节码文件

使用JavaCompile进行编译，代码很简单

/** * <p> * 编译Java文件 * </p> *  * @param path *            目录 */public static void compileFile(List<String> files) {try {JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();DiagnosticCollector<JavaFileObject> diagnostics = new DiagnosticCollector<JavaFileObject>();StandardJavaFileManager fileManager = compiler.getStandardFileManager(diagnostics, null, Charset.forName("UTF-8"));// 每个文件被保存在一个从JavaFileObject继承的类中Iterable<? extends JavaFileObject> compilationUnits = fileManager.getJavaFileObjectsFromStrings(files);JavaCompiler.CompilationTask task = compiler.getTask(null, fileManager,diagnostics, null, null, compilationUnits);// 编译<span style="white-space:pre"></span>task.call();fileManager.close();} catch (Exception e) {e.printStackTrace();}}
