1. JDK最低版本:JDK6 update 10。

2. 支持的最低JAVA规范更新:

GlassFish 3.1
Oracle WebLogic 10.3.4 (with JPA 2.0 patch applied)

如果你想要使用完全的Servlet3.0特性,下面这些版本的容器完全兼容Servlet 3.0规范

Joda-Time 2.0 (2.3 recommended)
Hessian 4.0
XStream 1.4
Apache POI 3.5

5. 不推荐使用的类和方法
Jackson 1:

JacksonObjectMapperFactoryBean
MappingJacksonHttpMessageConverte

GenericTypeResolver:
GenericTypeResolver.getTargetType(MethodParameter methodParam)
GenericTypeResolver.resolveType(Type genericType, Map<TypeVariable, Type> map)
GenericTypeResolver.getTypeVariableMap(Class<?> clazz)

Burlap:
BurlapClientInterceptor
BurlapExporter
BurlapProxyFactoryBean
BurlapServiceExporter
SimpleBurlapServiceExporter

Jboss Classes:
JBossWorkManagerTaskExecutor
JBossWorkManagerUtils

Others:
AbstractJaxWsServiceExporter.setWebServiceFeatures(Object[] webServiceFeatures)

DefaultKeyGenerator

6. MVC namespace和schema更新,修改了2个属性的名:
enableMatrixVariables -> enable-matrix-variables
ignoreDefaultModelOnRedirect -> ignore-default-model-on-redirect

总的来看,如果JDK和Web Container没有问题的话,升级成本还是比较低的。
