@Override
public V call() throws Exception {
final UnitOfWork work = workProvider.get();
try {
work.begin();
return callable.call();
} catch (final Throwable t) {
log.error(t.getMessage(), t);

示例2: invoke
import com.google.inject.persist.UnitOfWork; //导入方法依赖的package包/类
public Object invoke(final MethodInvocation methodInvocation) throws Throwable {
UnitOfWork unitOfWork = unitOfWorkProvider.get();

}
