**示例【Spring MVC 使用AnnotationFormatterFactory格式化数据】**

**创建index.jsp**

<body>
    	<h4>测试表单数据格式化</h4>
    	<form action="register" method="post">
    		<table>
    			<tr>
    				<td>日期类型:</td>
    				<td><input type="text" name="birthday"></td>
    			</tr>
    			<tr>
    				<td>整数类型：</td>
    				<td><input type="text" name="total"></td>
    			</tr>
    			<tr>
    				<td>百分数类型：</td>
    				<td><input type="text" name="discount"></td>
    			</tr>
    			<tr>
    				<td>货币类型：</td>
    				<td><input type="text" name="money"></td>
    			</tr>
    			<tr>
    				<td></td>
    				<td><input type="submit" value="提交"></td>
    			</tr>
    		</table>
    	</form>
    </body>

**创建User**

package com.po;
    import java.util.Date;
    import org.springframework.format.annotation.DateTimeFormat;
    import org.springframework.format.annotation.NumberFormat;
    import org.springframework.format.annotation.NumberFormat.Style;
    public class User {
    	//日期类型
    	@DateTimeFormat(pattern="yyyy-MM-dd")
    	private Date birthday;
    	//正常数字类型
    	@NumberFormat(style=Style.NUMBER,pattern="#,###")
    	private int total;
    	//百分数类型
    	@NumberFormat(style=Style.PERCENT)
    	private double discount;
    	//货币类型
    	@NumberFormat(style=Style.CURRENCY)
    	private double money;
    	public Date getBirthday() {
    		return birthday;
    	}
    	public void setBirthday(Date birthday) {
    		this.birthday = birthday;
    	}
    	public int getTotal() {
    		return total;
    	}
    	public void setTotal(int total) {
    		this.total = total;
    	}
    	public double getDiscount() {
    		return discount;
    	}
    	public void setDiscount(double discount) {
    		this.discount = discount;
    	}
    	public double getMoney() {
    		return money;
    	}
    	public void setMoney(double money) {
    		this.money = money;
    	}
    	@Override
    	public String toString() {
    		return "User [birthday=" + birthday + ", total=" + total + ", discount=" + discount + ", money=" + money + "]";
    	}
    }

**创建UserController**

package com.controller;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.ModelAttribute;
    import org.springframework.web.bind.annotation.RequestMapping;
    import com.po.User;
    @Controller
    public class UserController {
    	@RequestMapping("/register")
    	public String register(@ModelAttribute User user,Model model) {
    		System.out.println(user);
    		model.addAttribute("user", user);
    		return "success";
    	}
    }

**配置springmvc-config.xml**

<mvc:annotation-driven/>
    
    <context:component-scan base-package="com.*" />
    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    	<property name="prefix" value=""></property>
    	<property name="suffix" value=".jsp" />
    </bean>

**创建success.jsp**

<body>
    	<form:form modelAttribute="user" action="">
    	<table>
    		<tr>
    			<td>日期类型：</td>
    			<td><form:input path="birthday"/></td>
    		</tr>
    		<tr>
    			<td>整数类型：</td>
    			<td><form:input path="total"/></td>
    		</tr>
    		<tr>
    			<td>百分数类型：</td>
    			<td><form:input path="discount"/></td>
    		</tr>
    		<tr>
    			<td>货币类型：</td>
    			<td><form:input path="money"/></td>
    		</tr>
    	</table>
    	</form:form>
    </body>

**启动Tomcat并访问index.jsp**
