请问SpringMVC如何把参数对象的字段转化为GET的URL方式?比如:title=你好&id=1&type=3

Question

public class Tag {
    private int id;
    private int fid;
    private String title;
    private int sort;
    private String type;
    private String type_name;
    private String uuid;
    private String url;
    private String description;
    private String src;
    private String createTime;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public int getFid() {
        return fid;
    }
    public void setFid(int fid) {
        this.fid = fid;
    }
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public int getSort() {
        return sort;
    }
    public void setSort(int sort) {
        this.sort = sort;
    }
    public String getType() {
        return type;
    }
    public void setType(String type) {
        this.type = type;
    }
    public String getType_name() {
        return type_name;
    }
    public void setType_name(String type_name) {
        this.type_name = type_name;
    }
    public String getUuid() {
        return uuid;
    }
    public void setUuid(String uuid) {
        this.uuid = uuid;
    }
    public String getUrl() {
        return url;
    }
    public void setUrl(String url) {
        this.url = url;
    }
    public String getDescription() {
        return description;
    }
    public void setDescription(String description) {
        this.description = description;
    }
    public String getSrc() {
        return src;
    }
    public void setSrc(String src) {
        this.src = src;
    }
    public String getCreateTime() {
        return createTime;
    }
    public void setCreateTime(String createTime) {
        this.createTime = createTime;
    }
}

@Controller
public class TagPageController {
    @RequestMapping("tag")
    public String navi(ModelMap modelMap,Tag tag,HttpServletRequest req) throws IOException{
        
        
        return "page";
    }
}

访问地址比如是 tag?title=你好&id=1&type=3
怎么在navi方法里对Tag tag参数转化为title=你好&id=1&type=3,
springmvc有没有提供什么快速的方法?
难道要自己手写实现?

Answer 1

现在都不查文档，直接伸手的吗？
spring ref
找@RequestParam
