Resttemplate 400 null exception
Asked on April 19, 2018
Im working on resttemplate post method.I need to post json string in this format,
{
"capabilities": [
"upload-license",
"publish-app-to-dashboard",
"access-all-models-in-tenant",
"tenant-admin",
"access-reports",
"access-editor",
"upload-license"
]
}
But when i post from spring Resttemplate it showing me 400 null.
I have created model for this.
modelname=Group
@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({
"name",
"status",
"tenantId"})
public class Group
{
private List<Capabilities> capabilities;
String tenantId;
String status;
String name;
String cap_id;
String groupId;
public String getTenantId() {
return tenantId;
}
public void setTenantId(String tenantId) {
this.tenantId = tenantId;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCap_id() {
return cap_id;
}
public void setCap_id(String cap_id) {
this.cap_id = cap_id;
}
public String getGroupId() {
return groupId;
}
public void setGroupId(String groupId) {
this.groupId = groupId;
}
public void setCapabilties(List<Capabilities> capabilities) {
if (capabilities!=null && capabilities.size()>0) {
ArrayList<Capabilities> list = new ArrayList<Capabilities>();
list.addAll(capabilities);
for (int i=(list.size()-1); i>=0; i--) {
Capabilities pn = list.get(i);
if (pn==null || (!hasText(pn.getName()))) {
list.remove(i);
}
}
capabilities = list;
}
this.capabilities = capabilities;
}
public List<Capabilities> getCapabilities() {
return capabilities;
}
public static final class Capabilities {
private String name;
public Capabilities(String capabilities) {
this.name = capabilities;
}
public Capabilities() {}
public String getName() {
return name;
}
public void setName(String capabilities) {
this.name = capabilities;
}
@Override
public String toString() {
return "{capabilities=" + name
+ "}";
}
}
}
Below code is my method.
@Override
public String addCapability(String groupId, String cap_id)
{
try {
System.out.println("groupId"+groupId);
System.out.println("cap_id"+cap_id);
Query query =
em.createQuery("SELECT aps.external_aps_capabilities_group_id FROM Usergroup aps where aps.external_uaa_groupid='"+groupId+"'");
System.out.println("query"+query.toString());
String activiti_groupid = (String) query.getSingleResult();
System.out.println("activiti_grpid"+activiti_groupid);
String url = activiti_URL+"/api/enterprise/admin/groups/"+activiti_groupid+"/capabilities";
String jsonString = "";
ObjectMapper mapper = new ObjectMapper();
System.out.println("cap_id"+cap_id);
System.out.println("url"+url);
Group.Capabilities capabilities=new Group.Capabilities();
capabilities.setName(cap_id);
List<Group.Capabilities> name =new ArrayList<Group.Capabilities>();
name.add(capabilities);
System.out.println("groupId"+groupId);
RestTemplate restTemplate = new RestTemplate();
Group objGroup = new Group();
objGroup.setCapabilties(name);
jsonString = mapper.writeValueAsString(objGroup);
System.out.println("objGroup"+objGroup);
System.out.println("jsonString"+jsonString);
HttpEntity<String> requestEntity = new HttpEntity<String>(jsonString, headers2);
String result = HttpRestClient.restTemplatePostMethod(requestEntity, url);
System.out.println("result="+result);
return result;
} catch (Exception ex) {
System.out.println("exception=="+ex.getMessage());
}
return "error";
}
When i work on this im getting Exception like this,
result=400 null
addCapability==400 null
