Example 1 with BooleanExpression

the class PermissionManagerImplementation method isAuthorized.

@Override
public boolean isAuthorized(PrivilegeObject source, PrivilegeObject target, OperationType operationType) {
    BooleanExpression expression = jTBObjectHierarchy.objectFrom.id.eq(jTBObjectPrivilege.objectTo.id).and(jTBObjectHierarchy.objectTo.id.eq(target.getId()));

Example 2 with BooleanExpression

use of com.querydsl.core.types.dsl.BooleanExpression in project JavaForFun by gumartinm.

the class AdDescriptionServiceImpl method queryDslExample.

// Extending CrudServiceImpl when we need some business logic. Otherwise we would be using
// the JPA repositories and nothing else :)
// In this case there is any business logic, but this is just an example.
/**
 * Using Querydsl. Giving some business logic to this service :)
 *
 * Querydsl: fluent interface done easy. There is no effort because it is already implemented.
 *
 * Criteria using Specifications requires some effort.
 *
 * See: de.spring.example.services.impl.AdServiceImpl

    final QAdDescription adDescription = QAdDescription.adDescription1;
