如何在java pojo类中解除json对象的deseralize? [英] How can I deseralize json object in java pojo class?
问题描述
我有一个简单的JSON语句,该类型非常需要。喜欢这个
I have a simple JSON statement which type is very per need. like this
{
actor:{name:"kumar",mbox:"kumar@gmail.com"}
verb :"completed"
}
或
{
actor:{name:["kumar","manish"],mbox:["kumar@gmail.com","manish@gmail.com"]}
verb :{
"id" : "http://adlnet.gov/expapi/verbs/completed",
"display" : {
"en-US" : "completed"
}
}
我正在使用POJO类来映射这个json字符串,并且pojo类代码被赋予了bleow
I am using using POJO class to map this json string and pojo class code is given bleow
@JsonProperty("actor")
Actor actor;
@JsonProperty("verb")

this.actor = actor;

public void setObjVerb(Verb objVerb) {
this.objVerb = objVerb;

@JsonIgnore

this.verb = verb;

String mbox_sha1sum;
@JsonProperty("openid")

@JsonProperty("account")
Account account;
public String getObjectType() {

public Account getAccount() {

public void setAccount(Account account) {
this.account = account;
}
public static class Account {
@JsonProperty("homePage")
String homePage;
@JsonProperty("name")
String name;
public String getHomePage() {

public void setDisplay(Map<String, String> display) {

}
我正在使用jaxb和jakson。我正在实现webservice来处理json语句
所以我使用bean类来映射json。但是当我用来映射这个json时,它会给出以下异常
I am using jaxb and jakson. I am implementing the webservice to handle the json statement so I use the bean class to map with json. But when I use to map this json then it gives the following exceptions
org.codehaus.jackson.map.JsonMappingException:带有名称的属性mbox有两个条目。
org.codehaus.jackson.map.JsonMappingException : property with the name "mbox" have two entry.
定义一个合适的bean结构,使其直接映射到beans类
Define a proper bean structure so it directly mapped to the beans class
推荐答案
尝试只留下 @JsonProperty(mbox)ArrayList< String> listMbox;
字段(不需要 @JsonProperty(mbox)
)
String mbox;
并添加 Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY = true
到Jackson对象映射器配置。
Try to leave only @JsonProperty("mbox") ArrayList<String> listMbox;
field (don't need @JsonProperty("mbox")
String mbox;
)
and add Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY=true
to Jackson object mapper config.
因此在反序列化中它将能够同时获得两个数组和单个元素。
So in deserialization it will be able to get as both array and single element.
