单对象校验
实体类UserInfo.java
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.NotNull;
import java.io.Serializable;
import java.util.Date;
@Data
public class UserInfo implements Serializable {
@ApiModelProperty(value = "标题", required = true)
@NotEmpty(message = "名称不能为空")
private String title;
@ApiModelProperty(value = "创建时间", required = true)
@NotNull(message = "创建时间不能为空")
private Date createTime;
}
其中message
用于提示语内容
控制层 UserApi.java
import javax.validation.Valid;
@ApiOperation(value = "测试接口")
@ApiImplicitParam(name = "data", value = "数据", required = true, dataType = "UserInfo", paramType = "body")
@PostMapping
public ResultBean<Boolean> businessStatus(@RequestBody @Valid UserInfo data) {
//业务操作
return ResultBean.build();
}
特别注意:@RequestBody
跟@Valid
顺序必须如上所示!
全局异常拦截 GlobalExceptionHandler.java
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;
import javax.management.MBeanException;
/**
* 全局异常处理
* 作用在所有注解了@RequestMapping的控制器的方法上
**/
@RestControllerAdvice
public class GlobalExceptionHandler {
private static final Logger logger = LoggerFactory.getLogger(GlobalExceptionHandler.class);
@ExceptionHandler(MethodArgumentNotValidException.class)
public ResultBean paramException(MethodArgumentNotValidException ex) {
logger.error(ex.getMessage(), ex);
return ResultBean.build(110, ex.getBindingResult().getFieldError().getDefaultMessage());
}
}
特别注意:ex.getBindingResult().getFieldError().getDefaultMessage()) 获取之前绑定的
message`内容
集合对象校验(List<Object>
)
添加ValidList.java
import javax.validation.Valid;
import java.util.*;
public class ValidList<E> implements List<E> {
@Valid
private List<E> list = new ArrayList<>();
public List<E> getList() {
return list;
}
public void setList(List<E> list) {
this.list = list;
}
@Override
public int size() {
return list.size();
}
@Override
public boolean isEmpty() {
return list.isEmpty();
}
@Override
public boolean contains(Object o) {
return list.contains(o);
}
@Override
public Iterator<E> iterator() {
return list.iterator();

@Override
public Object[] toArray() {
return list.toArray();
}
@Override

return list.toArray(a);
}
@Override
public boolean add(E e) {
return list.add(e);
}
@Override

return list.remove(o);
}
@Override

return list.contains(c);
}
@Override

return list.addAll(c);

@Override
public boolean addAll(int index, Collection<? extends E> c) {
return list.addAll(index, c);
}
@Override
public boolean removeAll(Collection<?> c) {
return list.removeAll(c);
}
@Override
public boolean retainAll(Collection<?> c) {
return list.retainAll(c);
}
@Override
public void clear() {
list.clear();
}
@Override
public E get(int index) {
return list.get(index);
}
@Override

@Override

@Override

@Override
