小编给大家分享一下SpringMVC表单标签知识点有哪些，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！
一.首先我们先做一个简单了例子来对Spring MVC表单表单标签的使用有一个大致的印象，然后再结合例子对各个标签介绍一下如何使用。
1.首先，在com.demo.web.models包中添加一个模型TagsModel内容如下：
package com.demo.web.models;
import java.util.List;
import java.util.Map;
public class TagsModel{
private String username;
private String password;
private boolean testBoolean;
private String[] selectArray;
private String[] testArray;
private Integer radiobuttonId;
private Integer selectId;
private List selectIds;
private Map testMap;
private String remark;
public void setUsername(String username){
this.username=username;
}
public void setPassword(String password){
this.password=password;
}
public void setTestBoolean(boolean testBoolean){
this.testBoolean=testBoolean;
}
public void setSelectArray(String[] selectArray){
this.selectArray=selectArray;
}
public void setTestArray(String[] testArray){
this.testArray=testArray;
}
public void setRadiobuttonId(Integer radiobuttonId){
this.radiobuttonId=radiobuttonId;
}
public void setSelectId(Integer selectId){
this.selectId=selectId;
}
public void setSelectIds(List selectIds){
this.selectIds=selectIds;
}
public void setTestMap(Map testMap){
this.testMap=testMap;
}
public void setRemark(String remark){
this.remark=remark;
}
public String getUsername(){
return this.username;
}
public String getPassword(){
return this.password;
}
public boolean getTestBoolean(){
return this.testBoolean;
}
public String[] getSelectArray(){
return this.selectArray;
}
public String[] getTestArray(){
return this.testArray;
}
public Integer getRadiobuttonId(){
return this.radiobuttonId;
}
public Integer getSelectId(){
return this.selectId;
}
public List getSelectIds(){
return this.selectIds;
}
public Map getTestMap(){
return this.testMap;
}
public String getRemark(){
return this.remark;
}
} 2.其次，在包com.demo.web.controllers添加一个TagsController内容如下：
package com.demo.web.controllers;
import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.demo.web.models.TagsModel;
@Controller
@RequestMapping(value = "/tags")
public class TagsController {
@RequestMapping(value="/test", method = {RequestMethod.GET})
public String test(Model model){
if(!model.containsAttribute("contentModel")){
TagsModel tagsModel=new TagsModel();
tagsModel.setUsername("aaa");
tagsModel.setPassword("bbb");
tagsModel.setTestBoolean(true);
tagsModel.setSelectArray(new String[] {"arrayItem 路人甲"});
tagsModel.setTestArray(new String[] {"arrayItem 路人甲","arrayItem 路人乙","arrayItem 路人丙"});
tagsModel.setRadiobuttonId(1);
tagsModel.setSelectId(2);
tagsModel.setSelectIds(Arrays.asList(1,2));
Map map=new HashMap();
map.put(1, "mapItem 路人甲");
map.put(2, "mapItem 路人乙");
map.put(3, "mapItem 路人丙");
tagsModel.setTestMap(map);
tagsModel.setRemark("备注...");
model.addAttribute("contentModel", tagsModel);
}
return "tagstest";
}
} 3.最后，在views文件夹下添加视图tagstest.jsp内容如下：
