# springMVC校验

#### 1. 导入校验jar文件

![](WebContent/Images/1.png)

```

hibernate-validator-4.3.0.Final.jar

jboss-logging-3.1.0.CR2.jar

validation-api-1.0.0.GA.jar

```

#### 2. 在spring-mvc.xml中配置校验器

	

![](WebContent/Images/2.png)

```xml

	

	

	

	

	

		

		

			

				classpath:CustomerValidationMessages

			

		

		

		

		

		

		

		

```

#### 3. 在src路径下配置错误信息文件CustomerValidationMessages.properties

![](WebContent/Images/3.png)

```properties

emp.empno = \u96C7\u5458\u7F16\u53F7\u957F\u5EA6\u5FC5\u987B\u4E3A4

emp.ename = \u96C7\u5458\u540D\u79F0\u5FC5\u987B\u7531\u4E0B\u5212\u7EBF\u3001\u6570\u5B57\u3001\u5B57\u6BCD\u7EC4\u6210\uFF0C\u957F\u5EA6\u5FC5\u987B\u57286-10\u4F4D\u4E4B\u95F4

emp.salary = \u85AA\u6C34\u5FC5\u987B\u5927\u4E8E1000\uFF0C\u5C0F\u4E8E99999

```

#### 4. 在spring-mvc.xml中校验器注入到处理器适配器中

		

```xml

```

#### 5. 在Emp.java添加校验规则

![](WebContent/Images/4.png)

```Java

public class Emp {

	/**雇员编号*/

	@Min(value=1000,message="{emp.empno}")

	@Max(value=9999,message="{emp.empno}")

	private int empno;

	

	/**雇员姓名*/

	@Pattern(regexp="[0-9a-zA-Z_]{6,10}",message="{emp.ename}")

	private String ename;

	

	/**职位*/

	@NotEmpty(message="{emp.job}")

	private String job;

	

	/**上级经理*/

	@Min(value=1000,message="{emp.mgr}")

	@Max(value=9999,message="{emp.mgr}")

	private int mgr;

	

	/**入职日期*/

	@NotNull(message="{emp.hiredate}")

	private Date hiredate;

	

	/**薪水*/

	@Min(value=1000,message="{emp.salary}")

	@Max(value=99999,message="{emp.salary}")

	private double salary;

	

	/**奖金*/

	@Min(value=1000,message="{emp.comm}")

	@Max(value=99999,message="{emp.comm}")

	private double comm;

}

```

#### 6. 在EmpController.java中捕获错误信息

![](WebContent/Images/5.png)

```Java

@RequestMapping("/insertEmp")

public String insertEmp(Model model,@Valid Emp emp,BindingResult bindingResult)

{

	//判断是否有错误结果

	if(bindingResult.hasErrors())

	{

		//获取错误结果

		List errorList = bindingResult.getAllErrors();

		/*for (ObjectError error : errorList) {

			System.err.println(error.getDefaultMessage());

		}*/

		

		//将错误结果保存在request作用域

		model.addAttribute("errorList", errorList);

		

		//跳转回新增界面，并显示错误信息

		return "empInsert";

		

	}

	

	System.out.println("新增用户的信息：" + emp);

	

	return "success";

}

```	

#### 7. 在empInsert.jsp中显示错误信息

![](WebContent/Images/6.png)

```Jsp



	

		${error.defaultMessage}


	



```

#### 7. 效果如下
