sturts2批量提交

• 数组/容器的处理:

  • 对于数组和容器，sturts可以直接将表单数据转化为对应的数据类型

  • jsp页面

    <form action="add.action" method="post">
        username:<input type="text" name="name"/>
        <br>
        hobbies:<input type="checkbox" name="hobbies" value="football"/>football
        <input type="checkbox" name="hobbies" value="basketball"/>basketball
        <input type="checkbox" name="hobbies" value="tabletennis"/>tabletennis
        <br>
        game:<input type="checkbox" name="games" value="lol"/>lol
        <input type="checkbox" name="games" value="qqt"/>qqt
        <input type="checkbox" name="games" value="dota"/>dota
        <br>
        <input type="submit" value="submit"/>
    </form>

  • action类

    public class UserAction {
        private String name;
        private String[] hobbies; // 使用数组
        private List<String> games; // 使用容器
    
        public String execute() {
            System.out.println("name: " + name);
            System.out.print("hobbies:");
            for(String s : hobbies) {
                System.out.print(" " + s);
            }
            System.out.print("\ngames: " + games );
            return Action.SUCCESS;
        }
    
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public String[] getHobbies() {
            return hobbies;
        }
        public void setHobbies(String[] hobbies) {
            this.hobbies = hobbies;
        }
        public List<String> getGames() {
            return games;
        }
        public void setGames(List<String> games) {
            this.games = games;
        }   
    }

• 集合对象处理

  • 需要自定义拦截器，目前还不会写QAQ
