java - 如何在 java 中修复 Mass Assignment : Insecure Binder Configuration (API Abuse, Structural)

Question

我有一个 Controller 类，其中包含以下两种查找医生的方法(上下文已更改)。获取Mass Assignment: Insecure Binder Configuration (API Abuse, Structural) 两种方法都出现错误。

@Controller
@RequestMapping(value = "/findDocSearch")
public class Controller {

    @Autowired
    private IFindDocService findDocService;

    @RequestMapping(value = "/byName", method = RequestMethod.GET)
    @ResponseBody
    public List<FindDocDTO> findDocByName(FindDocBean bean) {
        return findDocService.retrieveDocByName(bean.getName());
    }

    @RequestMapping(value = "/byLoc", method = RequestMethod.GET)
    @ResponseBody
    public List<FindDocDTO> findDocByLocation(FindDocBean bean) {
        return findDocService.retrieveDocByZipCode(bean.getZipcode(),
        bean.getDistance());
    }
}

我的 Bean 是:

public class FindDocBean implements Serializable {
    private static final long serialVersionUID = -1212xxxL;

    private String name;
    private String zipcode;
    private int distance;

    @Override
    public String toString() {
        return String.format("FindDocBean[name: %s, zipcode:%s, distance:%s]",
                name, zipcode, distance);
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getZipcode() {
        return zipcode;
    }

    public void setZipcode(String zipcode) {
        this.zipcode = zipcode;
    }

    public int getDistance() {
        return distance;
    }

    public void setDistance(int distance) {
        this.distance = distance;
    }

根据目前发现的所有建议，他们建议仅通过以下方式限制具有必需参数的 bean:

final String[] DISALLOWED_FIELDS = new String[]{"bean.name", "bean.zipcode", };

@InitBinder
public void initBinder(WebDataBinder binder) {
    binder.setDisallowedFields(DISALLOWED_FIELDS);

但我的问题是 bean 的所有 3 个参数都将用在 Controller 上提供的任一方法中。

有人可以为此提出一些解决方案吗？提前致谢。

InitBinder 可用于方法。你可以试试这个。

@InitBinder("findDocByName")
public void initBinderByName(WebDataBinder binder) {
    binder.setDisallowedFields(new String[]{"distance","zipcode"});
}


@InitBinder("findDocByLocation")
public void initBinderByZipCode(WebDataBinder binder) {
    binder.setDisallowedFields(new String[]{"distance","name"});
}
