我在用
javaparser(https://github.com/javaparser/javaparser)和
javasymbolsolver(https://github.com/javaparser/javasymbolsolver)。
解析Java源代码。我正在寻找一个从.java文件创建基本报告以列出方法签名的方法,如果它们包括完整的Java类型,那就太好了。
这是javaparser'visit'演示和javasymbolsolver演示的基本合并,但是我遇到了麻烦。
炸毁“ getType”呼叫,
Exception in thread "main" java.lang.UnsupportedOperationException: com.github.javaparser.ast.type.ClassOrInterfaceType
at me.tomassetti.symbolsolver.javaparsermodel.JavaParserFacade.getTypeConcrete(JavaParserFacade.java:392)
这是(无效)代码,
static CombinedTypeSolver combinedTypeSolver;
public static void main(String[] args) throws Exception {
combinedTypeSolver = new CombinedTypeSolver();
combinedTypeSolver.add(new JreTypeSolver());
combinedTypeSolver.add(new JarTypeSolver("C:/source.jar"));
combinedTypeSolver.add(new JavaParserTypeSolver(new File("C:/src")));
FileInputStream in = new FileInputStream("C:/src/source.java");
CompilationUnit cu = JavaParser.parse(in);
new MethodVisitor().visit(cu, null);
}
private static class MethodVisitor extends VoidVisitorAdapter<Void> {
public void visit(MethodDeclaration n, Void arg) {
Node node = n.getType();
System.out.println(node);
TypeUsage typeOfTheNode = JavaParserFacade.get(combinedTypeSolver).getType(node);
super.visit(n, arg);
}
}
最佳答案
我建议将ReflectionTypeSolver
添加到您的CombinedTypeSolver
中。
然后,要获取所有MethodDeclaration的列表,我将使用
List<MethodDeclaration> l = Navigator.findAllNodesOfGivenClass(cu, MethodDeclaration.class);
然后,将每个MethodDeclaration(JavaParser)包装在JavaParserMethodDeclaration中,像这样
for(MethodDeclaration md : l){
System.out.println(new JavaParserMethodDeclaration(mdec, facade.getTypeSolver()).getQualifiedSignature());
}
