I have an Entity Transaction as following : 

@Entity
class Transaction extends AbstractEntity<Long>{
        private static final long serialVersionUID = 7222139865127600245L;
        //other attributes

    @ElementCollection(fetch = FetchType.EAGER, targetClass = java.lang.String.class)
    @CollectionTable(name = "transaction_properties", joinColumns = @JoinColumn(name = "p_id"))
    @MapKeyColumn(name = "propertyKey")
    @Column(name = "propertyValue")
    private Map<String, String> properties;

    //getters and setters
}

So, my Database Table for transaction_properties is 

mysql> desc transaction_properties;
+---------------+--------------+------+-----+---------+-------+
| Field         | Type         | Null | Key | Default | Extra |
+---------------+--------------+------+-----+---------+-------+
| p_id          | bigint(20)   | NO   | PRI |         |       |
| propertyValue | varchar(255) | YES  |     | NULL    |       |
| propertyKey   | varchar(255) | NO   | PRI |         |       |
+---------------+--------------+------+-----+---------+-------+
3 rows in set (0.00 sec)

Now, I want to search entity Transaction with key and value.

    Path<Map<String, String>> propertiesPath = root.get("properties");
    Path<String> propertyKeyPath = propertiesPath.<String> get("propertyKey"); //where m getting error
    Path<String> propertyValuePath = propertyKeyPath.<String> get("propertyValue");
    p = cb.and(p, cb.and(cb.like(propertyKeyPath, "%" + searchTrxnKey + "%"), cb.like(propertyValuePath, "%" + searchTrxnValue + "%")));

But am getting error for Path<String> propertyKeyPath = propertiesPath.<String> get("propertyKey"); as following :
