Spring HashMap value-ref Key points to value ref name

Question

Here is my HashMap in spring context which uses value-ref :

<util:map id="generalDAOMap" map-class="java.util.HashMap">
        <entry key="1" value-ref="userDAO" />
        <entry key="2" value-ref="accountsDAO" />
        <entry key="3" value-ref="settingsDAO" />       
</util:map>
<bean id="userDAO"
        class="com.test.myproj.dao.impl.UserDAOImpl" />
<bean id="accountsDAO"
        class="com.test.myproj.dao.impl.AccountsDAOImpl" />
<bean id="settingsDAO"
        class="com.test.myproj.dao.impl.SettingsDAOImpl" />

In my Java class i have autowired the "generalDAOMap" as below:

@AutoWired

private Map<String,GeneralDAO> generalDAOMap;

//getters and setters follows

When i print the map value its as follows :

{userDAO = com.test.myproj.dao.impl.UserDAOImpl@164d6ae,accountsDAO = com.test.myproj.dao.impl.AccountsDAOImpl@ed9382 , settingsDAO = com.test.myproj.dao.impl.SettingsDAOImpl@ed9586}

but the Key values should be "1","2" and "3" , why its getting replaced as "userDAO ","settingsDAO " and "accountsDAO ", due to which when i use getGeneralDAOMap.get("1") it returns null. Kindly help.

Answer 1

Can you try using @Resource instead of using @Autowired ?

Spring docs says this,

As a specific consequence of this semantic difference, beans that are themselves defined as a collection or map type cannot be injected through @Autowired, because type matching is not properly applicable to them. Use @Resource for such beans, referring to the specific collection or map bean by unique name.
