（急）Spring3 注解@ResponseBody如何返回正确的JSON数组5

利用Spring3注解返回JSON数组

	@RequestMapping(value = "/test")
	@ResponseBody
	public List testHandler(HttpServletRequest request){
		Fault fault = new Fault();
		fault.setPlineId(1);
		fault.setPlineName("s1");
		Fault fault1 = new Fault();
		fault1.setPlineId(2);
		fault1.setPlineName("ppppp");
		
		List list = new ArrayList();
		list.add(fault);
		list.add(fault1);
		return list;
	}

前台采用jquery EasyUI的Grid控件，结果一直无法输出数据，查看后台，发现Spring3有数据输出，但输出的数据格式似乎不符合标准的JSON数据格式

Eclipse控制台输出：

[DEBUG]-2011-01-12 11:39:36,406-org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter -Written [[{PLineID=1, MachineID=1, FaultID=9, FaultCount=12, plineName=纸板1, machineName=整理机1, stateName=故障}, {PLineID=1, MachineID=1, FaultID=10, FaultCount=2, plineName=纸板1, machineName=2整理机, stateName=故障}]] as "application/json" using [org.springframework.http.converter.json.MappingJacksonHttpMessageConverter@d51a54]

配置一：
@RequestMapping(value="/sys/functiontree",produces="text/plain;charset=UTF-8")
@ResponseBody
public String testHandler()

配置二：

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <ref bean="stringHttpMessageConverter" />
                <ref bean="jsonHttpMessageConverter" />
    
            </list>
        </property>
    </bean>

    <bean id="stringHttpMessageConverter" class="org.springframework.http.converter.StringHttpMessageConverter" >
     <property name = "supportedMediaTypes">
                     <list>
                         <value>text/plain;charset=UTF-8</value>
                     </list>
                </property>
    </bean>
    <bean id="jsonHttpMessageConverter"
        class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>application/json</value>
            </list>
        </property>
    </bean>
