Spring Jbpm6集成问题

我尝试集成Spring和JBPM6，但是根据https://github.com/droolsjbpm/droolsjbpm-integration/tree/6.1.0.Final/kie-spring/src/test/resources/jbpm/local-emf的配置使用基于Java的样式配置，但在创建RuntimeEviromentFactoryBean时遇到无法解决的循环引用错误，这里列出我的配置

DataConfig.java 

@Configuration
@EnableJpaRepositories(basePackages = { "com.test.spring.config.repository" })
@EnableTransactionManagement
public class DataConfig {
@Bean
public DataSource devDataSource() {
    HikariConfig config = new HikariConfig();
    config.setJdbcUrl("jdbc:h2:mem:spring-jbpm");
    config.setUsername("jbpm");
    config.setPassword("jbpm);
    config.setDriverClassName("org.h2.Driver");
    return new HikariDataSource(config);
}

@Bean
@Autowired
public LocalContainerEntityManagerFactoryBean entityManagerFactory(
        DataSource datasource) {
    LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
    emf.setDataSource(datasource);
    HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
    hibernateJpaVendorAdapter.setShowSql(true);
    emf.setJpaVendorAdapter(hibernateJpaVendorAdapter);
    emf.setPackagesToScan("org.jbpm.persistence.processinstance",
            "org.drools.persistence.info", "org.jbpm.process.audit",
            "org.jbpm.persistence.correlation",
            "org.jbpm.runtime.manager.impl.jpa",
            "org.jbpm.services.task.impl.model",
            "org.jbpm.services.task.audit.impl.model");
    emf.setJpaPropertyMap(getJpaProperties());
    emf.setMappingResources("META-INF/Taskorm.xml",
            "META-INF/TaskAuditorm.xml");
    return emf;
}

private Map<String, ?> getJpaProperties() {
    Map<String, Object> p = new HashMap<String, Object>();
    p.put("hibernate.max_fetch_depth", 3);
    p.put("hibernate.hbm2ddl.auto", "create");
    p.put("hibernate.dialect", "org.hibernate.dialect.H2Dialect");
    p.put("hibernate.id.new_generator_mappings", false);
    return null;

}

@Bean
@Autowired
public PlatformTransactionManager transactionManager(
        EntityManagerFactory emf) throws NamingException {
    return new JpaTransactionManager(emf);
}

@Bean
@Autowired
public EntityManager entityManager(EntityManagerFactory emf) {
    return emf.createEntityManager();
}

JbpmConfig.java 

@Configuration
public class JbpmConfig {

@Bean
@Autowired
public RuntimeEnvironmentFactoryBean runtimeEnvironmentFactoryBean(
        EntityManagerFactory emf, PlatformTransactionManager tm) {

    RuntimeEnvironmentFactoryBean ref = new RuntimeEnvironmentFactoryBean();

    ref.setType("DEFAULT");
    ref.setEntityManagerFactory(emf);
    ref.setTransactionManager(tm);
    // ref.setKbaseName("kbase");
     ref.setAssets(getAssets());
    return ref;

}

// @Bean
// @Autowired
// public RuntimeEnvironment runtimeEnvironment(
// RuntimeEnvironmentFactoryBean ref) throws Exception {
// return (RuntimeEnvironment) ref.getObject();
// }

// @Bean
// @Autowired
// public RuntimeManagerFactoryBean runtimeManagerFactoryBean(
// RuntimeEnvironment re) {
// RuntimeManagerFactoryBean rmf = new RuntimeManagerFactoryBean();
// rmf.setIdentifier("spring-rm");
// rmf.setRuntimeEnvironment(re);
// rmf.setType("PER_PROCESS_INSTANCE");
// return rmf;
// }

// @Bean
// @Autowired
// public TaskServiceFactoryBean taskServiceFactoryBean(
// EntityManagerFactory emf, PlatformTransactionManager tm) {
// TaskServiceFactoryBean tsf = new TaskServiceFactoryBean();
// tsf.setEntityManagerFactory(emf);
// tsf.setTransactionManager(tm);
// return tsf;
// }

// @Bean
// @Autowired
// public JPAAuditLogService logService(EntityManagerFactory emf) {
// JPAAuditLogService logService = new JPAAuditLogService(emf);
// return logService;
//
// }

private Map<Resource, ResourceType> getAssets() {
    Map<Resource, ResourceType> assets = new HashMap<Resource, ResourceType>();
    assets.put(ResourceFactory
            .newClassPathResource("jbpm/processes/sample.bpmn"),
            ResourceType.BPMN2);
    return assets;
}

好吧，在我更改配置后，它可以运行，代码如下

DataConfig.java 

@Configuration
@EnableJpaRepositories(basePackages = { "com.test.spring.config.repository" })
@EnableTransactionManagement
public class DataConfig {
@Bean
public DataSource devDataSource() {
    HikariConfig config = new HikariConfig();
    config.setJdbcUrl("jdbc:h2:mem:spring-jbpm");
    config.setUsername("jbpm");
    config.setPassword("jbpm);
    config.setDriverClassName("org.h2.Driver");
    return new HikariDataSource(config);
}

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
    emf.setDataSource(dataSource());
    HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
    hibernateJpaVendorAdapter.setShowSql(true);
    emf.setJpaVendorAdapter(hibernateJpaVendorAdapter);
    emf.setPackagesToScan("org.jbpm.persistence.processinstance",
            "org.drools.persistence.info", "org.jbpm.process.audit",
            "org.jbpm.persistence.correlation",
            "org.jbpm.runtime.manager.impl.jpa",
            "org.jbpm.services.task.impl.model",
            "org.jbpm.services.task.audit.impl.model");
    emf.setJpaPropertyMap(getJpaProperties());
    emf.setMappingResources("META-INF/JBPMorm.xml","META-INF/Taskorm.xml",
            "META-INF/TaskAuditorm.xml");
    return emf;
}

private Map<String, ?> getJpaProperties() {
    Map<String, Object> p = new HashMap<String, Object>();
    p.put("hibernate.max_fetch_depth", 3);
    p.put("hibernate.hbm2ddl.auto", "create");
    p.put("hibernate.dialect", "org.hibernate.dialect.H2Dialect");
    p.put("hibernate.id.new_generator_mappings", false);
    return p;

}

@Bean
public PlatformTransactionManager transactionManager() throws NamingException {
    return new JpaTransactionManager(entityManagerFactory().getObject());
}

JbpmConfig.java 

@Configuration
public class JbpmConfig {
@Autowired
private EntityManagerFactory emf;

@Autowired
private PlatformTransactionManager tm;

@Bean
public RuntimeEnvironmentFactoryBean runtimeEnvironment() {

    RuntimeEnvironmentFactoryBean ref = new RuntimeEnvironmentFactoryBean();

    ref.setType("DEFAULT");
    ref.setEntityManagerFactory(emf);
    ref.setTransactionManager(tm);
    // ref.setKbaseName("kbase");
     ref.setAssets(getAssets());
    return ref;

}

@Bean(name = "runtimeManager", destroyMethod = "close")
public RuntimeManagerFactoryBean runtimeManager() {
    RuntimeManagerFactoryBean rmf = new RuntimeManagerFactoryBean();
    rmf.setIdentifier("spring-rm");
    try {
        rmf.setRuntimeEnvironment((RuntimeEnvironment) runtimeEnvironment()
                .getObject());
    } catch (Exception e) {
        e.printStackTrace();
    }
    rmf.setType("PER_PROCESS_INSTANCE");
    return rmf;
}

@Bean
public TaskServiceFactoryBean taskServiceFactoryBean() {
    TaskServiceFactoryBean tsf = new TaskServiceFactoryBean();
    tsf.setEntityManagerFactory(emf);
    tsf.setTransactionManager(tm);
    return tsf;
}

private Map<Resource, ResourceType> getAssets() {
    Map<Resource, ResourceType> assets = new HashMap<Resource, ResourceType>();
    assets.put(ResourceFactory
            .newClassPathResource("jbpm/processes/sample.bpmn"),
            ResourceType.BPMN2);
    return assets;
}
