Jackson annotations being ignored in Spring

Question

I'm trying to make a property in a domain class hidden but it keeps appearing in the outputted JSON. I'm using Jackson 2.0 and Spring 3.1.1

Output of /users/1:

{"id":1,"password":null,"email":"[email protected]","firstName":"John","lastName":"Smith"}

My domain class:

@Entity
public class User {
    private String mPassword;
    ... 
    @JsonIgnore
    public String getPassword() {
        return mPassword;
    }

    public void setPassword(String password) {
        mPassword = password;
    }
    ...
}

My springmvc config:

...
<mvc:annotation-driven/>
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
    <property name="favorPathExtension" value="true" />
    <property name="mediaTypes">
        <map>
            <entry key="json" value="application/json"/>
        </map>
    </property>
    <property name="defaultContentType" value="application/json"/>
    <property name="defaultViews">
        <list>
            <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />
        </list>
    </property>
</bean>
...

And my controller:

@Controller
@RequestMapping("/users")
public class UserController {
    private UserService mUserService;

    public UserController(){}

    @Inject
    public void setUserController(UserService userService){
        mUserService=userService;
    }

    @RequestMapping(value="/{id}", method=RequestMethod.GET)
    public void getUser(@PathVariable("id") long id, Model model){
        model.addAttribute(mUserService.getUser(id));
    }
}

Support for Jackson 2 has been added to Spring 3.1.2 (backported from Spring 3.2 - SPR-9507). Just upgrade your project from Spring 3.1.1 to Spring 3.1.2, and Jackson 2 works with the configuration you already have.
