Question

我有一个带有一些注释的pojo，如下所示。

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;
import com.fasterxml.jackson.annotation.JsonProperty;
import javax.validation.constraints.*;


import java.util.Date;

@XmlRootElement()
@XmlAccessorType(XmlAccessType.FIELD)

public class Author {
@NotNull
private int contactId;

@Min(value = 1000000000000L, message = "EAN is less than 13 digits")
@Max(value = 9999999999999L, message = "EAN is greater than 13 digits")
@JsonProperty("EAN")
private long EAN;


@NotNull(message = "First name is compulsory")   
private String person_firstname;

@NotNull(message="Email Address is compulsory")     
@Pattern(regexp = "^([a-zA-Z0-9_\\-\\.]+)@([a-zA-Z0-9_\\-\\.]+)\\.([a-zA-Z]{2,5})$", message = "Email Address is not a valid format")   
private String person_email;
// getters and setters
}

下面是我的验证员。

public class AuthorValidator implements Processor {

public void process(Exchange exchange) throws Exception {

    String exceptions="Exception Occured";
    try {           
    String jsonBody = exchange.getIn().getBody(String.class);
    ObjectMapper objectMapper = new ObjectMapper();
    TypeReference<List<Author>> mapType = new TypeReference<List<Author>>() {};
    List<Author> authorList = objectMapper.readValue(jsonBody, mapType);

    ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
    Validator validator = factory.getValidator();   

    for(Author au : authorList){

    Set<ConstraintViolation<Author>> violations = validator.validate(au);       
    for (ConstraintViolation<Author> violation : violations) {
        exceptions+=violation.getMessage(); 


    }
    }
    }catch(Exception e)
    {
        exceptions=e.getMessage();
    }
    exchange.getOut().setBody(exceptions);

}

当我在eclipse中测试类时，它给了我一个正确的验证输出。但是当我试图从servicemix调用它时抛出以下错误。

Unable to create a Configuration, because no Bean Validation provider could 
be found. Add a provider like Hibernate Validator (RI) to your classpath.

我尝试安装所有捆绑包但仍然存在错误。 Apache ServiceMix :: Bundles :: hibernate-validator：5.0.2 Hibernate验证器引擎骆驼豆验证 Bean Validation API

所有必需的罐子都在构建路径中

是否可以让我知道我需要在servicemix上安装哪些软件包才能使验证工作。

Answer 1

我已经在apache骆驼中实现了同样的效果。使用以下链接表示相同。

具有验证者和杰克逊的依赖项：

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-bean-validator</artifactId>
    <version>${camel.version}</version>         
</dependency>

 <dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-jackson</artifactId>
    <version>${camel.version}</version>
</dependency>

和带注释的类：

import javax.validation.constraints.Size;

import org.hibernate.validator.constraints.NotBlank;

public class Author {

    @NotBlank
    @Size(min = 1, max = 20)
    private int contactId;
}

我肯定会使用unmarshall + bean-validator端点，而忘了unmarshall-validation Processor：

<unmarshal>
    <json library="Jackson"
            unmarshalTypeName="Author" />
</unmarshal>
<to uri="bean-validator://author" />
...
