问题描述

我正在尝试隐藏域类中的属性，但它一直出现在输出的JSON中。我正在使用Jackson 2.0和Spring 3.1.1

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

输出/ users / 1：

Output of /users/1:

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

我的域类：

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

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

我的springmvc配置：

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>
...

我的控制器：

@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));
    }
}

推荐答案

问题是Spring不适用于Jackson 2.0。这已通过以下方式解决：

The problem is that Spring doesn't work with Jackson 2.0. This has been solved in the following way:

<bean id="jacksonMessageConverter"
          class="own.implementation.of.MappingJacksonHttpMessageConverter"/>

<bean class="org.springframework.web.servlet.mvc
             .annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <ref bean="jacksonMessageConverter"/>
            </list>
        </property>
        <property name="requireSession" value="false"/>
    </bean>

并且own.implementation.of.MappingJacksonHttpMessageConverter基于此：

And the own.implementation.of.MappingJacksonHttpMessageConverter is based on this:

但是使用来自Jackson 2.0的ObjectMapper和其他Jackson类而不是Jackson 1。*

But use ObjectMapper and other Jackson classes from Jackson 2.0 instead of Jackson 1.*
