Wolf-Dieter Fink created ISPN-9866:
--------------------------------------
Summary: Query is failing if custom classes are used inside of the cache
Key: ISPN-9866
URL: https://issues.jboss.org/browse/ISPN-9866
Project: Infinispan
Issue Type: Bug
Components: Embedded Querying, WildFly modules
Affects Versions: 9.4.5.Final
Environment: Wildfly server with ISPN modules and ISPN subsystem to configure
caches
Reporter: Wolf-Dieter Fink
A simple query for a cache which contains User classes will fail for queries with the
error below.
UserData class for the cache:
public class Test implements Serializable {
private int testId;
public Test(){}
public Test(int myId) {this.testId = myId;}
public int getTestId() {return animalId;}
public void setTestId(int testId) { this.testId = testId;}
}
Simple EJB for test
@Singleton
@Startup
public class TestInfinispanQuery4EAPConfig {
@Resource(lookup =
"java:jboss/datagrid-infinispan/container/jdg-container/cache/EAPcache")
private Cache<String, Object> cache;
@PostConstruct
public void LoadDBToMemory() {
cache.put("1", new Test(2, 0));
cache.put("2", new Test(2, 0));
cache.put("3", new Test(1, 0));
QueryFactory queryFactory = Search.getQueryFactory(cache);
Query q = queryFactory.from(Test.class).having("testId").eq(2).build();
int size = q.getResultSize();
System.out.println("result = " + size);
}
}
