Question

Have no experience with Spring beans injection.

<beans:bean id="ModeService"
        class="<path>Service">
    <beans:property name="Mode" value="true"/>
</beans:bean>

<beans:bean id="Filter"
       class="<path>.RequestFilter">
    <custom-filter position="FIRST" />
</beans:bean>

How to inject ModeService bean into Filter bean ?

ok, I’ve got injection in Spring thx @William
So have:

<beans:bean id="maintenanceModeService"
        class="<path>.MaintenanceService">
    <beans:property name="maintenanceMode" value="true"/>
</beans:bean>

<beans:bean id="maintenanceFilter"
       class="<path>.MaintenanceRequestFilter">
    <custom-filter position="FIRST" />
    <beans:property name="modeService" ref="maintenanceModeService"/>
</beans:bean>

In MaintenanceService, I’ve append setter/getter for invoking variable:

boolean maintenanceMode;

public void setMaintenanceMode(boolean mode)
{
    this.maintenanceMode = mode;
}

public boolean getMaintenanceMode()
{
    return maintenanceMode;
}

And append setter/getter into MaintenanceRequestFilter:

boolean modeService;

public void setModeService(MaintenanceService maintenanceMode)
{
    this.modeService = maintenanceMode;
}

public MaintenanceService getMaintenanceMode()
{
    return modeService;
}

And then invoke modeService in doFilter()

But smth wrong…

Answer 1

<beans:bean id="Filter" class="<path>.RequestFilter">
    <custom-filter position="FIRST" />
    <beans:property name="modeService" ref="ModService"/>
</beans:bean>

And you should have a getter/setter method in your class

class RequestFilter{
    public void setModeService(ModService modService){
        // some set code here
    }

    public ModeService getModeService(){
        // some set code here
        return modService;
    }
}
