ContentNegotiatingViewResolver多种输出格式实例: json/jsp/xml/xls/pdf

本例用的是javaConfig配置

以pizza为例。

json输出需要用到的包：

jackson-databind 2.4.1.3

jackson-annotations 2.4.1

　　

pdf需要用到的包：

lowagie itext 4.2.1

　　

xls需要用到的包：

Apache POI 3.10-beta2

　　

xml包

spring-oxm

　　

访问地址：

http://localhost:8080/gugua9/hello/aaa.xml

http://localhost:8080/gugua9/hello/aaa.json

http://localhost:8080/gugua9/hello/aaa

http://localhost:8080/gugua9/hello/aaa.xls

http://localhost:8080/gugua9/hello/aaa.pdf

pom.xml配置：
