Question

这是我的测试用例，它抛出了预期的org.springframework.batch.item.validator.ValidationException。下面的评论员帮助了http://springbatchbyexample.blogspot.com/2014/09/validation-input-data.html

     @Autowired
 MdwValidatingItemProcessor mdwValidatingItemProcessor;

 @Test(expected = ValidationException.class)
 public void notNullOnProperty(){
     MecMdw mecMdw = new MecMdw();
     //nothing set, property "lob" is null

     mdwValidatingItemProcessor.process(mecMdw);         
 }

我有以下使用javax.validation.constraints.NotNull的域对象：

 import javax.validation.constraints.NotNull;


public class MecMdw {

@NotNull
private String lob;

Spring和Spring Batch的版本是：

    <spring.version>4.1.7.RELEASE</spring.version>      
    <spring.batch.version>3.0.4.RELEASE</spring.batch.version>

我在pom.xml中添加了以下库：

    <dependency>
       <groupId>org.hibernate</groupId> 
       <artifactId>hibernate-validator</artifactId> 
       <version>4.0.2.GA</version> 
    </dependency>
    <dependency>
        <groupId>org.aspectj</groupId> 
        <artifactId>aspectjweaver</artifactId> 
        <version>1.5.4</version> 
    </dependency>
    <dependency>
        <groupId>org.aspectj</groupId> 
        <artifactId>aspectjrt</artifactId> 
        <version>1.5.4</version> 
    </dependency>
    <dependency>
        <groupId>javax.validation</groupId>
        <artifactId>validation-api</artifactId>
        <version>1.0.0.GA</version>
    </dependency>

在我的Spring Batch作业XML中，我已经连接了验证器：

<bean id="mdwValidatingItemProcessor" class="com.my.itemprocessor.MdwValidatingItemProcessor">
    <property name="validator">
        <bean class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" /> 
    </property>
</bean>

MdwValidatingItemProcessor看起来如下，对于这个测试用例，我可以在调试时进入process方法：

public class MdwValidatingItemProcessor implements ItemProcessor<MecMdw, MecMdw> {  

private Validator validator;  

public void setValidator(Validator validator) {  
     this.validator = validator;  
}  

@Override 
public MecMdw process(MecMdw item) throws Exception {  

     BindingResult results = BindAndValidate(item);  
     if (results.hasErrors())  
          buildValidationException(results);  

     //TODO write to kickout table
     return item;  
}  

private BindingResult BindAndValidate(MecMdw item) {  
     DataBinder binder = new DataBinder(item);  
     binder.setValidator(validator);  

     binder.validate();  

     return binder.getBindingResult();  

}  

private void buildValidationException(BindingResult results) {  
     StringBuilder msg = new StringBuilder();  
     for (ObjectError error : results.getAllErrors()) {  
          msg.append("-*-*-*- \n" + error.toString() + "-*-*-*- \n");  
     }  
     throw new ValidationException(msg.toString());  
}

使用Spring版本4.1.7.RELEASE和Spring Batch版本3.0.4.RELEASE在我的Spring Batch项目中不激活Bean验证
