Two-way Association is converted to JSON. because both sides are associated, an endless loop is formed. Add the following annotations to the object:

@ Entity
@ Table (name = "t_dl_urbandetectunit ")
@ Jsonignoreproperties (value = {"urbanroadinfo "})

/*@ManyToOne(cascade=CascadeType.ALL)@JoinColumn(name="URBANID")public UrbanRoadInfo getUrbanRoadInfo() {return urbanRoadInfo;}public void setUrbanRoadInfo(UrbanRoadInfo urbanRoadInfo) {this.urbanRoadInfo = urbanRoadInfo;}*/

Then urbanroadinfo is not included in the JSON string.
