json数据转化出错.
-------------------出错的代码--------------------------------
ObjectMapper objectMapper = new ObjectMapper();
//String ss = "{\"where\":\" if (\\\"\'浙江省\'\\\" = \\\"\'\'\\\", 1=0, cus.state in (\'浙江省\')) or if (\\\"\'\'\\\"=\\\"\'\'\\\", 1=0, cus.city in (\'\')) or if (\\\"\'\'\\\"=\\\"\'\'\\\", 1=0, cus.district in (\'\')) \"}";
String ss = "{\"where\":\" if (\"'浙江省'\" = \"''\", 1=0, cus.state in ('浙江省')) or if (\"''\"=\"''\", 1=0, cus.city in ('')) or if (\"''\"=\"''\", 1=0, cus.district in ('')) \"}";
objectMapper.configure(JsonParser.Feature.ALLOW_SINGLE_QUOTES , true);
Map<String,Object> sql_map = objectMapper.readValue(ss,HashMap.class);
System.out.println(sql_map.get("where"));
