问题描述
尊敬的Spring Java专业人士
请帮我解决这个问题:我在春天有一个定制服务,运行我的wildfly服务器上没有任何错误。 但是当我执行以下更新请求时,尽管我发送了控制器中指定的格式,但我收到了400错误的请求
在我的控制器内:
@RequestMapping(value = "/user/updatefilters/{Id}", method = RequestMethod.POST)
public Response updateFilter(@PathVariable("Id") Long Id, @RequestBody @Valid Filter Filter) {
FilterService.updateFilter(Id, Filter);
HashMap<String, Object> response = new HashMap<>();
response.put("messages", null);
response.put("success", Boolean.valueOf(true));
return Response.instance().friendlyName("filter-updated").object(response).statusCode(HttpStatus.OK);
}
在我的服务文件中:
public void updateFilter(Long Id,Filter Filter) {
List<Filter> currentFilter = FilterRepo.getFilters(Id, Filter.getFilterId().longValue(),null);
currentFilter.get(0).setLabel(Filter.getLabel());
FilterRepo.save(currentFilter.get(0));
for (FilterField FilterField : Filter.getFilterFields()) {
FilterField currentFilterField = FilterFieldRepo.getFilterField(FilterField.getfieldId());
if (currentFilterField != null) {
currentFilterField.setfield(FilterField.getfield());
currentFilterField.setTypeId(FilterField.getTypeId());
FilterFieldRepo.save(currentFilterField);
}
}
}
在我的存储库中:
public List<Filter> getFilterList(Long Id, String type) {
List<Filter> FilterField = FilterFieldRepo.getFilterFields(Id,type);
return FilterField;
}
public void updateFilter(Long Id,Filter Filter) {
List<Filter> currentFilter = FilterRepo.getFilters(Id, Filter.getFilterId().longValue(),null);
currentFilter.get(0).setLabel(Filter.getLabel());
FilterRepo.save(currentFilter.get(0));
for (FilterField FilterField : Filter.getFilterFields()) {
FilterField currentFilterField = FilterFieldRepo.getFilterField(FilterField.getfieldId());
if (currentFilterField != null) {
currentFilterField.setfield(FilterField.getfield());
currentFilterField.setTypeId(FilterField.getTypeId());
FilterFieldRepo.save(currentFilterField);
}
}
}
请注意,在我的实体内,我添加了一个临时列表,如下所示:
@Transient
private List<FilterField> filterFields;
更新:这是我的Filter类,我在netbeans中生成了crud,但是手动添加了transuent列表:
@Entity
@Table(schema="hitmeister",name = "filters")
@NamedQueries({
@NamedQuery(name = "Filter.findAll", query = "SELECT s FROM Filter s"),
@NamedQuery(name = "Filter.findByFilterId", query = "SELECT s FROM Filter s WHERE s.filterId = :filterId"),
@NamedQuery(name = "Filter.findById", query = "SELECT s FROM Filter s WHERE s.Id = :Id"),
@NamedQuery(name = "Filter.findByLabel", query = "SELECT s FROM Filter s WHERE s.label = :label"),
@NamedQuery(name = "Filter.findByInsertionDate", query = "SELECT s FROM Filter s WHERE s.insertionDate = :insertionDate"),
@NamedQuery(name = "Filter.findByIsActive", query = "SELECT s FROM Filter s WHERE s.isActive = :isActive"),
@NamedQuery(name = "Filter.findByType", query = "SELECT s FROM Filter s WHERE s.type = :type")})
public class Filter implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "filter_id")
private Integer filterId;
@Basic(optional = false)
@NotNull
@Column(name = "id")
private int Id;
@Basic(optional = false)
@NotNull
@Size(min = 1, max = 500)
@Column(name = "label")
private String label;
@Basic(optional = true)
@Column(name = "insertion_date")
@Temporal(TemporalType.TIMESTAMP)
private Date insertionDate;
@Column(name = "is_active")
private Boolean isActive;
@Basic(optional = false)
@NotNull
@Size(min = 1, max = 20)
@Column(name = "type")
private String type;
@Transient
private List<FilterField> filterFields;
public Filter() {
}
public Filter(Integer filterId) {
this.filterId = filterId;
}
public Filter(Integer filterId, int Id, String label, Date insertionDate, String type) {
this.filterId = filterId;
this.Id = Id;
this.label = label;
this.insertionDate = insertionDate;
this.type = type;
}
public Integer getFilterId() {
return filterId;
}
public void setFilterId(Integer filterId) {
this.filterId = filterId;
}
public int getId() {
return Id;
}
public void setuserId(int Id) {
this.userId = userId;
}
public String getLabel() {
return label;
}
public void setLabel(String label) {
this.label = label;
}
public Date getInsertionDate() {
return insertionDate;
}
public void setInsertionDate(Date insertionDate) {
this.insertionDate = insertionDate;
}
public Boolean getIsActive() {
return isActive;
}
public void setIsActive(Boolean isActive) {
this.isActive = isActive;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
@Override
public int hashCode() {
int hash = 0;
hash += (filterId != null ? filterId.hashCode() : 0);
return hash;
}
@Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Filter)) {
return false;
}
Filter other = (Filter) object;
if ((this.filterId == null && other.filterId != null) || (this.filterId != null && !this.filterId.equals(other.filterId))) {
return false;
}
return true;
}
@Override
public String toString() {
return " Filter #"+ filterId ;
}
public List<FilterField> getFilterFields() {
return filterFields;
}
public void setFilterFields(List<FilterField> filterFields) {
this.filterFields = filterFields;
}
}
如果您需要我的实体代码,我也可以发布它。谢谢!
1楼
我的第一个建议: (OP尝试了,但没有用,她正在发送POST请求)
如下更改映射,我认为应该没问题。 来自浏览器地址栏的请求是GET请求。
如下所示,当服务器无法理解客户端正在发送的请求时,HTTP 400出现了,在您的情况下,您正在发送GET,但是服务器除了POST之外没有其他用于GET的消息,所以返回400。
10.4.1 400错误的请求
由于语法格式错误,服务器无法理解该请求。 客户不应在没有修改的情况下重复请求。
代码修复:
@RequestMapping(value = "/user/updatefilters/{Id}", method = RequestMethod.GET)
我的第二个建议:
我不是Spring专家,但是这是我的2美分,您可以根据提供的JSON对象和过滤器映射进行尝试-(1.)将userId
更改为Id
,(2。) insertionDate
userId
设置为NULL,而不是空字符串。
确保您的JSON字符串变量与Filter类映射区分大小写,并且它们的值与引用类型兼容。

您的请求格式不是Spring期望的格式,或者Filter
验证之一失败了。
添加org.springframework.validation.Errors
参数并转储值以找出验证失败的原因。
public Response updateFilter(@PathVariable("Id") Long Id, @RequestBody @Valid Filter Filter, Errors filterErrors) {
您可以使用curl或网络监视工具来嗅探实际流量,以确保HTTP事务确实如您所想。
编辑:在您的注释之一中查看了JSON之后,我认为这在您的JSON字段名称中将变成大写/小写。
可以将“ Id”更改为“ id”,将“ FilterId”更改为“ filterId”,或者使用@XmlElement(name = "Id")
和@XmlElement(name = "FilterId")
注释Filter
字段。
Java Bean属性名称区分大小写。
编辑2: Filter.setuserId(int Id)
也被损坏。
您需要一个setId()
方法来反序列化Bean,并且需要更改该方法,以便它存储传递的参数,而不仅仅是将userId
设置为其自身。
