Question

我在项目中使用了spring boot和post man。在控制器中，我使用了使所有类别看起来像这样的方法：

@GetMapping(value = "/category")
@ResponseStatus(HttpStatus.OK)
public List<ReadableCategory> findAllCategories(@RequestParam(value = "filter", required = false) List<String> filter, MerchantStore store, Language language) {
    return categoryService.findCategories(store, 0, language, filter);
}

MerchanStore：

public class MerchantStore implements Auditable {

private final static String DEFAULT_STORE = "DEFAULT";

@Id
@Column(name = "MERCHANT_ID", unique = true, nullable = false)
@TableGenerator(name = "TABLE_GEN", table = "SM_SEQUENCER", pkColumnName = "SEQ_NAME",
        valueColumnName = "SEQ_COUNT", pkColumnValue = "STORE_SEQ_NEXT_VAL")
@GeneratedValue(strategy = GenerationType.TABLE, generator = "TABLE_GEN")
@JsonProperty(

        "merchant_id")
private Integer id;

@Column(name = "STORE_NAME", nullable = true, length = 100)
@JsonProperty(value = "store_name")
private String storeName;

@Pattern(regexp = "^[a-zA-Z0-9_]*$")
@Column(name = "STORE_CODE", nullable = true, unique = true, length = 100)
@JsonProperty(value = "merchant_id")
private String code;

@Column(name = "STORE_PHONE", length = 50)
private String storePhone;

@Column(name = "STORE_ADDRESS")
private String storeAddress;

@Column(name = "STORE_CITY", length = 100)
private String storeCity;

@Column(name = "STORE_POSTAL_CODE", length = 15)
private String storePostcode;

@ManyToOne(fetch = FetchType.LAZY, targetEntity = Country.class)
@JoinColumn(name = "COUNTRY_ID", nullable = true)
private Country country;

@ManyToOne(fetch = FetchType.LAZY, targetEntity = Zone.class)
@JoinColumn(name = "ZONE_ID", nullable = true)
private Zone zone;

@Column(name = "STORE_STATE_PROV", length = 100)
private String storeStateProvince;

@Column(name = "WEIGHTUNITCODE", length = 5)
private String wightUnitCode = MeasureUnit.LB.name();

@Column(name = "SEIZEUNITCODE", length = 5)
private String seizeUnitCode = MeasureUnit.IN.name();

@Column(name = "IN_BUSINESS_SINCE")
private LocalDate inBusinessSince = LocalDate.now();

@Transient
private String dateBusinessSince;

@ManyToOne(fetch = FetchType.LAZY, targetEntity = Language.class)
@JoinColumn(name = "LANGUAGE_ID", nullable = false)
private Language defaultLanguage;

@ManyToMany(fetch = FetchType.LAZY)
@JoinTable(name = "MERCHANT_LANGUAGE")
private List<Language> languages = new ArrayList<>();

//some thing fields and get/set methods

Language.class

@Id
@Column(name = "LANGUAGE_ID")
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;

@Embedded
private AuditSection auditSection = new AuditSection();

@Column(name = "CODE", nullable = false)
private String code;

@Column(name = "SORT_ORDER")
private Integer sortOrder;

@OneToMany(mappedBy = "defaultLanguage",targetEntity = MerchantStore.class)
@ToString.Exclude
@JsonIgnoreProperties
private List<MerchantStore> storesDefaultLanguage;

@ManyToMany(mappedBy = "languages",targetEntity = MerchantStore.class,fetch = FetchType.EAGER)
@ToString.Exclude
@JsonIgnoreProperties
private List<MerchantStore> stores = new ArrayList<>();

public String getCode() {
    return code;
}

当我向邮递员请求时，其外观如下： http://localhost:8585/api/v1/id=1&storeName=2&code=3&languages=1,2,3

它有效，但是因为当我请求所有字段时，我的班级MerchanStore有很多字段。示例：10字段，我的网址很长很复杂。我有两个问题：

是否有更好的方法可以发布参数而不将其放在上面使用GET请求（而非发布请求）的网址。
当我输入id = 1时，因为MerchanStore类包含id和语言也包含id，它会赋予相同的值1。如何指定特定值
带有ID的MerchanStore和带有ID的语言。

Answer 1

是否存在一种更好的方法来发布参数，而无需使用GET请求（而不是Post Request）将其放在url上。

不。对请求参数使用GET表示您的URL可以被添加书签。尤其是出于搜索或过滤目的，它非常方便且有用。

当我输入id = 1时，由于类MerchanStore包含id，而语言也包含id，它将相同的值设为1。带有ID的MerchanStore和带有ID的语言。

对此我一无所知，也许您可以将其发布为新问题。

Answer 2

您可以使用 @ModelAttribute 。试试这个：
