校验

第一步：pom.xml添加

<dependency>
                <groupId>javax.validation</groupId>
                <artifactId>validation-api</artifactId>
                <version>1.1.0.Final</version>
            </dependency>
    
            <dependency>
                <groupId>org.hibernate</groupId>
                <artifactId>hibernate-validator</artifactId>
                <version>5.1.0.Final</version>
            </dependency>
    
            <dependency>
                <groupId>org.hibernate</groupId>
                <artifactId>hibernate-validator-annotation-processor</artifactId>
                <version>5.1.0.Final</version>
            </dependency>

第二步：新建validation.properties文件，这个是作为全局设置的

第三步：在applicationContext.xml中

<context:property-placeholder
                location="classpath*:jdbc.properties,
        			  classpath*:redis.properties,
        			  classpath:validation.properties,
        			  classpath:httpclient.properties"/>

第五步：新建分组接口AdvisoryValid，（用于当一个实体类需要校验的字段过多时，但是在某个controller类中又不需要所有的属性都校验）

public interface AdvisoryValid {
    
    }

第六步：在pojo类中需要校验的属性进行设置

@NotNull(message = "咨询人advisoryId为空",groups = {AdvisoryValid.class})
        private Integer advisoryId;  //咨询id
    	
        private String advisoryName; //咨询人姓名
    
        @NotEmpty(message = "咨询人电话不能为空",groups = {AdvisoryValid.class})
        @Pattern(regexp = "^[1][3,4,5,7,8][0-9]{9}$",message = "咨询人电话格式不正确",groups = {AdvisoryValid.class})
        private String advisoryPhone; //咨询人电话
        
        @NotEmpty(message = "老人姓名不能为空",groups = {AdvisoryValid.class})
        @Size(min=1,max=20,message = "老人姓名长度最小为1,最大为20",groups = {AdvisoryValid.class})

第六步：在controller类中使用校验@validated

@Authorization
        @ResponseBody
        @RequestMapping(value = "/advisoryAdd" , method = RequestMethod.POST)
        public JsonResult<Advisory> advisoryAdd(@Validated(value = {AdvisoryValid.class}) Advisory advisory , BindingResult br){
        	String [] validateParam = {"advisoryPhone","oldName"};
            Map<String, String> errorMap = ValidateUtil.getErrorMap(br, validateParam);
            if(errorMap != null && errorMap.size() != 0){
    			/* 返回参数校验错误详情 */
                return new JsonResult(false, "添加拜访记录参数错误", errorMap);
            }
        	int n = advisoryService.insert(advisory);
        	if(n <= 0){
        		return new JsonResult(false,"添加失败",n);
    		}
            return new JsonResult(true,"添加成功",n);
        }

注意点：validated和BindingResult是成对出现的

validateParam只需要写出该controller方法需要进行校验的属性，不需要列出实体类中进行注解的所有属性

message可以是对应的配置文件里面的属性值（message="\{oldman.name.empty\}"），

也可以自己定义，eg：message="手机号格式不正确"
