MVC jQuery json CSS Bean

通过maven pom.xml引入包

<dependency>
            <groupId>org.codehaus.jackson</groupId>
            <artifactId>jackson-core-asl</artifactId>
        </dependency>

        <dependency>
            <groupId>org.codehaus.jackson</groupId>
            <artifactId>jackson-mapper-asl</artifactId>
        </dependency>

版本为1.0.0

注意不能同时引用多个版本的jar包。

在spring mvc 配置文件中加入

<bean id="messageAdapter"
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <util:list>
                <bean
                    class="org.springframework.http.converter.StringHttpMessageConverter" />
                <bean
                    class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
            </util:list>
        </property>
    </bean>

控制层

@RequestMapping("/g/getItems")
    @ResponseBody
    public Map<String, Object> getItems(){
        log.info("firstIndex:"+firstindex);
        log.info("maxresult:"+maxresult);
        QueryResult<AskOne> r = resourcesService.getScrollData(AskOne.class,
                firstindex, maxresult);
        List<AskOne> items = r.getResultlist();
        if(items!=null&&items.size()>0){
            for(AskOne a : items){
                String title = a.getAskTitle();
                if(title!=null&&title.length()>30){
                    title = title.substring(0, 30);
                    a.setAskTitle(title);
                }
            }
        }
        long total = r.getTotalrecord();
        Map<String, Object> result = new HashMap<String, Object>();
        result.put("total", total);
        result.put("rows", items);
        return result;

    }
