我想根据身份验证甚至角色过滤对象属性。因此,例如,完整的用户配置文件将为经过身份验证的用户返回,并针对未经过身份验证的用户进行过滤。
我怎样才能实现它MappingJacksonHttpMessageConverter
?我已经为 Jaskon 声明了自定义 bean:
<bean id="objectMapper" class="com.example.CustomObjectMapper"/>
<bean id="MappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="objectMapper" ref="objectMapper"/>
</bean>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="order" value="1" />
<!-- <property name="customArgumentResolver" ref="sessionParamResolver"/> -->
<property name="webBindingInitializer">
<bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer">
<!-- <property name="conversionService" ref="conversionService" /> -->
<!-- <property name="validator" ref="validator" /> -->
</bean>
</property>
<property name="messageConverters">
<list>
<bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter" />
<bean class="org.springframework.http.converter.StringHttpMessageConverter" />
<bean class="org.springframework.http.converter.ResourceHttpMessageConverter" />
<bean class="org.springframework.http.converter.FormHttpMessageConverter" />
<ref bean="MappingJacksonHttpMessageConverter"/>
</list>
</property>
</bean>
注意:在控制器中,我将结果写为:
public void writeJson (Object jsonBean, HttpServletResponse response) {
MediaType jsonMimeType = MediaType.APPLICATION_JSON;
if (jsonConverter.canWrite(jsonBean.getClass(), jsonMimeType)) {
try {
jsonConverter.write(jsonBean, jsonMimeType, new ServletServerHttpResponse(response));
} catch (IOException m_Ioe) {
} catch (HttpMessageNotWritableException p_Nwe) {
} catch (Exception e) {
e.printStackTrace();
}
} else {
log.info("json Converter cant write class " +jsonBean.getClass() );
}
}
