java中json字符串怎么转json对象
StringjsonStr="[{'id':'11','parentId':'root','refObj':{'existType':'exist','deptType'...
String jsonStr ="[{'id':'11','parentId':'root','refObj':{'existType':'exist','deptType':'emp','treeNodeType':'dept'}]"

public static void test4() {
String jsonStr = "[{'id':'11','parentId':'root','refObj':{'existType':'exist','deptType':'emp','treeNodeType':'dept'}}]";
Gson gson = new Gson();
Type type = new TypeToken<List<Bean>>() {
}.getType();
List<Bean> list = gson.fromJson(jsonStr, type);
for (int i = 0; i < list.size(); i++) {
Bean bean = list.get(i);
// 这就是你需要的值
String existVal = bean.getRefObj().getExistType();
System.out.println(existVal);
}
}
class Bean {
private String id;
private String parentId;
private RefObj refObj;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getParentId() {
return parentId;
}
public void setParentId(String parentId) {
this.parentId = parentId;
}
public RefObj getRefObj() {
return refObj;
}
public void setRefObj(RefObj refObj) {
this.refObj = refObj;
}
@Override
public String toString() {
return "Bean [id=" + id + ", parentId=" + parentId + ", refObj=" + refObj + "]";
}
}
class RefObj {
private String existType;
private String deptType;
private String treeNodeType;
public String getExistType() {
return existType;
}
public void setExistType(String existType) {
this.existType = existType;
}
public String getDeptType() {
return deptType;
}
public void setDeptType(String deptType) {
this.deptType = deptType;
}
public String getTreeNodeType() {
return treeNodeType;
}
public void setTreeNodeType(String treeNodeType) {
this.treeNodeType = treeNodeType;
}
@Override
public String toString() {
return "RefObj [existType=" + existType + ", deptType=" + deptType + ", treeNodeType=" + treeNodeType + "]";
}
}
另外,你的json有错哦!在后面少了一个‘}’

String jsonStr ="{'id':'11','parentId':'root','refObj':{'existType':'exist','deptType':'emp','treeNodeType':'dept'}}";
JSONObject jsonObj = new JSONObject(jsonStr);
JSONObject refObj = new JSONObject(jsonObj.getString("refObj"));
String existType = refObj.getString("existType");
System.out.println(existType);
jar使用的是org.json.jar
