你需要使用ObjectMapper类来将字符串转换为JsonNode对象。以下是示例代码: java import com.fasterxml.jackson.databind.JsonNode; import com.fasterxml.jackson.databind.ObjectMapper; public class StringToJsonNodeExample { public static void main(String[] args) { String jsonString = "{\"name\":\"John\",...
importcom.fasterxml.jackson.databind.ObjectMapper;publicclassStringToJsonExample{publicstaticvoidmain(String[]args){StringjsonString="{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";ObjectMapperobjectMapper=newObjectMapper();try{// 将String转换为JSON对象JsonNodejsonNode=objectMapper.read...

Jackson是另一个常用的Java库，也可以实现string到json的转换。示例如下：```java String jsonString = "{\"name\":\"张三\",\"age\":20}";ObjectMapper objectMapper = new ObjectMapper();JsonNode jsonNode = objectMapper.readTree(jsonString);```二、json转string 在将json转换为string的过程中，同样可以...
Very simply, to parse the JSON String we only need anObjectMapper: @TestpublicvoidwhenParsingJsonStringIntoJsonNode_thenCorrect()throwsJsonParseException, IOException {StringjsonString="{"k1":"v1","k2":"v2"}";ObjectMappermapper=newObjectMapper();JsonNodeactualObj=mapper.readTree(jsonString); assert...

debug发现,jsonNode中的属性,都是两个双引号,故取得的属性值转为String再传入Mybatis的String参数,也是多了一个双引号的 解决方案: jsonNode的get方法后的toString方法后,再加上一句replaceAll()方法,替换掉多余的引号。 详情见图: 修改为: 增补:使用asText()方法也可达成同样的效果,比toString()再replaceAll()...
