常用配置
ObjectMapper objectMapper = new ObjectMapper(); objectMapper.configure(Feature.IGNORE_UNKNOWN,true); objectMapper.configure(Feature.WRITE_BIGDECIMAL_AS_PLAIN,true); objectMapper.configure(JsonParser.Feature.ALLOW_MISSING_VALUES,true); objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false); objectMapper.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES,false);//大小写脱敏 默认为false 需要改为tru
参考
com.fasterxml.jackson.databind.MapperFeature#ACCEPT_CASE_INSENSITIVE_PROPERTIES
使用注解方式：举例
public static void main(String[] args) throws IOException {
String x = "{\n"
+ " \"TToUserName\":\"gh_a5624dd2db4e\",\n"
+ " \"FFromUserName\":\"ochvq0Kn35VlnTAcIJ3fRBAZTQUY\""
+ " }";
ObjectMapper objectMapper = new ObjectMapper();
Result map = objectMapper.readValue(x, Result.class);
System.out.println(map);
objectMapper.writeValue(System.out,map);
}
private static class Result {
private String ToUserName;
private String FromUserName;
@JsonProperty("ToUserName")
public String getToUserName() {
return ToUserName;
}
@JsonProperty("TToUserName")
public void setToUserName(String toUserName) {
ToUserName = toUserName;
}
@JsonProperty("FromUserName")
public String getFromUserName() {
return FromUserName;
}
@JsonProperty("FFromUserName")
public void setFromUserName(String fromUserName) {
FromUserName = fromUserName;
}
}
Jackson 转换大小写问题
Jackson转换json时会把大写转换成小写
解决办法：
1、在变量时加上： @JsonProperty
2、在set/get方法加上：@JsonIgnore
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
