java - Mustache.java 传递 json 字符串

Question

我正在使用 Mustache.java 并希望插入 json 字符串而不是对象。我不确定为什么以前没有人遇到过这个问题。

// works since an 'Example' object is passed in
mustache.execute(new BufferedWriter(new FileWriter(objFile)), new Example()).flush();

// does not work since a json object is passed in directly
 JSONObject jsonObject = new JSONObject("{\n" +
            "  \"header\": \"Colors\",\n" +
            "  \"items\": [\n" +
            "      {\"name\": \"red\", \"first\": true, \"url\": \"#Red\"},\n" +
            "      {\"name\": \"green\", \"link\": true, \"url\": \"#Green\"},\n" +
            "      {\"name\": \"blue\", \"link\": true, \"url\": \"#Blue\"}\n" +
            "  ],\n" +
            "  \"empty\": false\n" +
            "}");
mustache.execute(new BufferedWriter(new FileWriter(objFile)), jsonObject).flush();

我找到了解决这个问题的方法!

可以从 json 字符串创建一个 HashMap 并将其传递给 Mustache.execute 方法。

//create map using gson    
Map<String,Object> gsonMap = new HashMap<String,Object>();
gsonMap = (Map<String,Object>) gson.fromJson(myJsonString, gsonMap.getClass());

//pass the hashmap instead of a class object
mustache.execute(new BufferedWriter(new FileWriter(objFile)), gsonMap).flush();
