java - 如何在 Spring Rest 中获取响应时限制 json 字段

Question

this the code:

@RequestMapping(value="/find/city={city}", method=RequestMethod.GET)
public List<Master_City> getCity(@PathVariable String city)
 {
    return City_Repository.findByCityLikeIgnoreCase(city);
 }

所有 JSON 字段都已显示。我只需要 2 个字段。

Answer 1

只需将 @JsonIgnore 注释添加到您不想发送的字段的 getter 中示例:

class MasterCity{
 private String contact;
  private String address;
     public String getContact() {
    return contact;
}

public void setContact(String contact) {
    this.contact = contact;
}
@JsonIgnore
public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}
}


@RequestMapping(value="/find/city={city}", method=RequestMethod.GET)
public List<Master_City> getCity(@PathVariable String city)
 {
    return City_Repository.findByCityLikeIgnoreCase(city);
 }

现在它将忽略该地址
