Guice grapher实用程序中有一个bug导致大多数或所有图形呈现损坏。是否有解决方法或修复此问题?

我稍微修改了@ wuppi的答案,也隐藏了类路径和长随机名称注释,使图形更加紧凑和可读。他的answer编辑后的代码如下:

我发现这个实用程序方法非常有用,它从来没有为我打错图。

关于style=invis错误:Guice grapher插件生成一个点文件,其中一些clases的样式是不可见的。下面发布的方法中的replaceAll()可以解决这个问题。其余代码与Guice示例几乎相同。

我已经整合了Scot对Guice 4.x的修复,其中包括Tim的答案:

public class Grapher {
    public static void main(String[] args) throws Exception {
        Grapher.graph4("filename.dot", Guice.createInjector(new MyModule()));
    }
    public static void graph4(String filename, Injector inj) throws Exception {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        PrintWriter out = new PrintWriter(baos);

        Injector injector = Guice.createInjector(new GraphvizModule());
        GraphvizGrapher renderer = injector.getInstance(GraphvizGrapher.class);
        renderer.setOut(out);
        renderer.setRankdir("TB");
        renderer.graph(inj);    

        out = new PrintWriter(new File(filename), "UTF-8");
        String s = baos.toString("UTF-8");
        s = fixGrapherBug(s);
        s = hideClassPaths(s);
        out.write(s);
        out.close();
    }

    public static String hideClassPaths(String s) {
        s = s.replaceAll("\\w[a-z\\d_\\.]+\\.([A-Z][A-Za-z\\d_\\$]*)", "$1");
        s = s.replaceAll("value=[\\w-]+", "random");
        return s;
    }

    public static String fixGrapherBug(String s) {
        s = s.replaceAll("style=invis", "style=solid");
        s = s.replaceAll("margin=(\\S+), ", " margin=\"$1\", ");
        return s;
    }
}

当然,您可以自由生成任何其他文件名:)

Guice 4.x将Jeff和Tim的解决方案结合起来的例子:

public class Grapher {
    public static void main(String[] args) throws Exception {
        Grapher.graph4("filename.dot", Guice.createInjector(new MyModule()));
    }
    public static void graph4(String filename, Injector inj) throws Exception {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        PrintWriter out = new PrintWriter(baos);

        Injector injector = Guice.createInjector(new GraphvizModule());
        GraphvizGrapher renderer = injector.getInstance(GraphvizGrapher.class);
        renderer.setOut(out);
        renderer.setRankdir("TB");
        renderer.graph(inj);    

        out = new PrintWriter(new File(filename), "UTF-8");
        String s = baos.toString("UTF-8");
        s = fixGrapherBug(s);
        s = hideClassPaths(s);
        out.write(s);
        out.close();
    }

    public static String hideClassPaths(String s) {
        s = s.replaceAll("\\w[a-z\\d_\\.]+\\.([A-Z][A-Za-z\\d_]*)", "");
        s = s.replaceAll("value=[\\w-]+", "random");
        return s;
    }

    public static String fixGrapherBug(String s) {
        s = s.replaceAll("style=invis", "style=solid");
        s = s.replaceAll("margin=(\\S+), ", " margin=\"$1\", ");
        return s;
    }
}

答案 2 :(得分:2)

使用最新版本的GraphViz时,我发现以下替换也有帮助(否则GraphViz拒绝打开文件):

s.replaceAll(" margin=(\\S+), ", " margin=\"$1\", ")

答案 3 :(得分:-1)

上面的hideClassPaths()方法中的第一个replaceAll过于热心 - 它删除了类名和包。它应该是

s = s.replaceAll("\\w[a-z\\d_\\.]+\\.([A-Z][A-Za-z\\d_\\$]*)", "$1");

请注意添加美元符号,因此这也适用于内部类名。
