Question

I have three hierarchical layers injected in Spring – rest, business logic and database operations. Junit tests for BL and DAO are working OK, when rest can inject only business logic ioc layer.

My supper class for junit tests:

import org.springframework.test.AbstractTransactionalSpringContextTests;

public class AbstractTest extends AbstractTransactionalSpringContextTests {
protected static final String path = "config/spring/applicationContext.xml";

/**
 * Disabled autowire by type 
 * Disabled dependency check
 */
public AbstractTest() {
    super();
    this.setAutowireMode(AUTOWIRE_BY_NAME);
    this.setDependencyCheck(false);
}

@Override
protected String[] getConfigLocations() {
    return new String[] {
            path
    };
}
}

So – rest calls business logic and this calls database operations. Nullpointer exception falls in business logic for database calls.

More info with example:
REST: getUser(id) calls
BL: getUserBO(id) calls
DAO: getUserDAO(id)

Nullpointer is thrown on getUserDAO in getUserBO method. This only happens with junit tests it is working deployed.

I found that it is a problem of struts2 rest class mapping. So Spring couldn’t inject…
