406 Not Acceptable in spring mvc

Question

I am building a web app in spring MVC.

I want to retrieve List of patient (collection) using Ajax. But it throws me error of 406 not acceptable

Jsp File

$(document).ready(function () {
                    $.ajax({
                        url: 'searchPatient',
                        //data: "uhid=" + $("#uhid").val() + "&type=" + $("#type").val(),
                        contentType: 'application/json',
                        dataType: 'json',
                        success: function (data) {
                            alert(data);
                        }
                    });
                });

** Controller File

@RequestMapping("/searchPatient")
    public @ResponseBody List<String> getPatient() 
    {
             List<String> s = new ArrayList<String>();
        s.add("hello");
        return s;
    }

How can I solve this error?

Answer 1

您的请求URI为http：//…/ HMIS / searchPatient，因此请确保将DispatcherServlet映射到/ HMIS / *或它已存在于控制器@RequestMapping中

Answer 2

I know this is an old question, but I also had this error an solved it adding the definition for MappingJacksonHttpMessageConverter like this:

<bean id="jsonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />

<!-- Bind the return value of the Rest service to the ResponseBody. -->
<bean
    class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
        <util:list id="beanList">
            <ref bean="jsonHttpMessageConverter" />          
        </util:list>
    </property>
</bean>
