Json系列之三 让你打印完美的json格式

public static String format(String jsonStr) {int level = 0;StringBuffer jsonForMatStr = new StringBuffer();for(int i=0;i<jsonStr.length();i++){char c = jsonStr.charAt(i);if(level>0&&'\n'==jsonForMatStr.charAt(jsonForMatStr.length()-1)){jsonForMatStr.append(getLevelStr(level));}switch (c) {case '{':case '[':jsonForMatStr.append(c+"\n");level++;break;case ',':jsonForMatStr.append(c+"\n");break;case '}':case ']':jsonForMatStr.append("\n");level–;jsonForMatStr.append(getLevelStr(level));jsonForMatStr.append(c);break;default:jsonForMatStr.append(c);break;}}return jsonForMatStr.toString();}private static String getLevelStr(int level){StringBuffer levelStr = new StringBuffer();for(int levelI = 0;levelI<level ; levelI++){levelStr.append("\t");}return levelStr.toString();}

通过以上format代码，，可以让你的json打印完美无缺

例子仍然是bean to json博文中的例子

{"addresses":[{"address":"address1","sameTest":[{"addresses":[],"age":0,"attrs":null,"baseAddress":null,"birthDay":null,"emptyStr":"","live":false,"name":"sameName","nullStr":"","sameTest":null}]},{"address":"address2","sameTest":[]}],"age":1,"attrs":{"key2":"value2","key1":"value1"},"baseAddress":{"address":"base address","sameTest":[]},"birthDay":{"date":10,"day":2,"hours":11,"minutes":11,"month":1,"seconds":4,"time":1423537864497,"timezoneOffset":-480,"year":115},"emptyStr":"","live":true,"name":"xxx","nullStr":"","sameTest":{"sameName2":"sameNamevalue2","sameName1":"sameNamevalue1"}}

谁是谁生命的点缀。
