解決spring4.x中的MappingJacksonHttpMessageConverter錯誤

在spring4.x中請用org.springframework.http.converter.json.MappingJackson2HttpMessageConverter代替。

並將maven依賴改成如下：

        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>2.5.1</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.5.1</version>
        </dependency>

我們用7-zip去查看spring-web-version.jar，確實已找不到MappingJacksonHttpMessageConverter這個class了。
