我正在使用使用jax-rs（球衣实现）的Java Rest服务。资源类调用一个名为myService的EJB。 myService调用另一个名为FirstDao的EJB。 FirstDao调用另一个名为SecondDao的EJB。全部在玻璃鱼5上运行。
资源类的内容具有以下方法和以下属性：
public class MyResource {
@EJB
private Service myService;
@POST
@Produces(MediaType.APPLICATION_JSON)
@Logged
@CorsHeaders
@Path("/index")
public Response createIndex(IndexRequest request) {
myService.indicise();
}
}
该服务的内容如下所示：
@Stateless
public class Service {
@EJB
private firstDao;
public void indicise() throws IOException {
firstDao.doSthg();
}
}
第一道内容如下：
@Stateless
public class FirstDao {
@EJB
private SecondDao secondDao;
public void doSthg() {
...very heavy and long lasting computation...
logger.info("saving words...");
try {
saveWords(terms);
}catch(Exception e) {
logger.severe("error e: " + e); //javax.ejb.EJBTransactionRolledbackException
Exception father;
while((father = (Exception) e.getCause()) != null) {
father = (Exception) e.getCause();
}
logger.severe("error e: " + father); //The control flow never reaches this line
}
logger.info("words saved");
}
public void saveWords(List<TermDto> terms) {
for(int i = 0; i < terms.size(); i++) {
logger.info("saving term " + i);
TermDto termDto = terms.get(i);
if(!secondDao.exists(termDto)) {
secondDao.saveTerm(termDto);
}
}
}
}
第二个岛的内容如下：
@Stateless
public class SecondDao {
@PersistenceContext(unitName = "blabla")
private EntityManager em;
public void saveTerm(...) {
em.persist(...);
}
public boolean exists(...) {
...very simple query...
}
}
javax.ejb.EJBTransactionRolledbackException：
由于在堆栈跟踪中没有指定异常，因此我认为是情况2）。因此，我在dao模块中修改了glassfish-ejb-jar：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-ejb-jar PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 EJB 3.1//EN" "http://glassfish.org/dtds/glassfish-ejb-jar_3_1-1.dtd">

我也在服务模块中修改了glassfish-ejb-jar：
