Spring Batch, JdbcExecutionContextDao java.util.Map $ Input deserializer error, xstream 1.4.1

I have a problem using Spring Batch 2.1.9: when I use jobExplorer.getJobExecution (jobExecutionId), I find a problem when the DAO deserializes the string, for example:

{"map":[{"entry":{"string":"parsedComparingDate","date":"2014-03-08 23:00:00.0 UTC"}}]}

from table BATCH_JOB_EXECUTION_CONTEXT using the method JdbcJobExecutionDao.getJobExecution().

I know that Spring package uses xstream 1.3, but in my Pom I:

  • spring -batch 2.1.9 ;
  • xstream 1.4.1 (inherited from smooks);
  • jettison 1.3.3 (inherited from cxf);

In addition, I read that xstream 1.3 does not work fine with Jettison 1.3.3, but using xstream 1.3 (excluding xstream 1.4.1 from pom) the operation works correctly, while using xstream 1.4.1 or major, I I find the following exception:

1) I saw the code, can I configure the XStreamExecutionContextStringSerializer to set reflectionProvider = null (this way it will not use the Provider)?

2) are there any other solutions to solve my problem?

thank

It is not possible to change the xstream version and the reset version because they are imported by other components (e.g. smooks).

JBoss .

, : spring -batch 2.2.0.RELEASE org.springframework.batch.core.repository.dao.DefaultExecutionContextSerializer XStream.

:

<bean id="batchDefaultSerializer" class="org.springframework.batch.core.repository.dao.DefaultExecutionContextSerializer" />

<bean id="jobRepository" class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="transactionManager" ref="batchTransactionManager" />
    <property name="lobHandler" ref="defaultLobHandler" />
    <property name="serializer" ref="batchDefaultSerializer" />
</bean>       

<bean id="jobExplorer"      
      class="org.springframework.batch.core.explore.support.JobExplorerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="serializer" ref="batchDefaultSerializer" />

- Jettison 1.2+ XStream, XStream Spring. , , . Jettison 1.2 XStream 1.4.7

Spring Boot 1.4.0 Spring Batch 3.0.7 , OSS Netflix b/c, XStreams 1.4.2.

I also use Java configuration instead of XML. Here is what I decided to solve the problem: In the @Configuration class:

   @Bean
   public ExecutionContextSerializer serializer()
   {
      return new Jackson2ExecutionContextStringSerializer();
   }

   @Bean
   @Autowired
   public JobRepository jobRepository( DataSource dataSource, 
                                       PlatformTransactionManager txManager ) throws Exception
   {
        JobRepositoryFactoryBean fac = new JobRepositoryFactoryBean();
        fac.setDataSource( dataSource );
        fac.setTransactionManager( txManager );
        fac.setSerializer( serializer() );
        fac.afterPropertiesSet();
        return fac.getObject();
   }

   @Bean
   @Autowired
   public JobExplorer jobExplorer( DataSource dataSource ) throws Exception
   {
      JobExplorerFactoryBean fac = new JobExplorerFactoryBean();
      fac.setDataSource( dataSource );
      fac.setSerializer( serializer() );
      fac.afterPropertiesSet();
      return fac.getObject();
   }

I use Postgres as the backup storage, so DefaultExecutionContextSerializer does not work as it tried to serialize binary instead of UTF-8 (JSON).
