如何使用ID检查HTTP GET方法的响应

Question

下面是我的控制器代码：

@RequestMapping(value = RestURIConstants.GET_APP_MENU_LIST, method = RequestMethod.GET)
public @ResponseBody ComListMaster getCommonMasterByMasterId(@PathVariable("listid") Integer listId)
{
    ComListMaster commonMaster = commonService.getCommonMasterList(listId);
    logger.debug("Calling master list");
    return commonMaster;
}

上面的代码给了我一个例外：

public class ComListMaster extends BaseModel implements java.io.Serializable

@Id
@Column(name = "LIST_ID")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer listId;

@Column(name = "LIST_DESC")
private String description;

@Column(name = "LIST_VALUE")
private String value;

@OneToMany(fetch = FetchType.EAGER, mappedBy = "comListMaster")
private Set<ComListDetails> comListDetails = new HashSet<ComListDetails>();

public Integer getListId()
{
    return listId;
}

public void setListId(Integer listId)
{
    this.listId = listId;
}

public String getDescription()
{
    return description;
}

public void setDescription(String description)
{
    this.description = description;
}

public String getValue()
{
    return value;
}

public void setValue(String value)
{
    this.value = value;
}

public Set<ComListDetails> getComListDetails()
{
    return comListDetails;
}

public void setComClientAddresses(Set<ComListDetails> comListDetails)
{
    this.comListDetails = comListDetails;
}

@Override
public String toString()
{
    return "ComListMaster [listId=" + listId + ", description=" + description + ", value=" + value
            + ", comListDetails=" + comListDetails + "]";
}

您可以删除（“listid”）--它不是强制性的，那么它就不会为输入字符串“{}”删除java.lang.NumberFormatException：。

@RequestMapping(value = "/{listId}", method = RequestMethod.GET)
public @ResponseBody ComListMaster getCommonMasterByMasterId(@PathVariable Integer listId)
{
    ComListMaster commonMaster = commonService.getCommonMasterList(listId);
    logger.debug("Calling master list");
    return commonMaster;
}
