Spring3 升级Spring 4

周末加班，想把spring3升级到spring4。 列一下遇到的坑

更换spring版本为

4.2.3

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>4.2.3.RELEASE</version>
</dependency>

加入spring support:

3中很多的扩展内容不需要引入support，但是4中分离的更彻底了，如果不分离，会很多ClassNotFound

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>4.2.3.RELEASE</version>
</dependency>

更换springmvc jackson依赖

spring mvc中如果过返回json需要依赖jackson的jar包，但是他升级到了2, 以前是codehaus.jackson，现在换成了fasterxml.jackson

<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.7.0</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.7.0</version>
</dependency>

同时修改spring mvc的配置文件：

<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="stringHttpMessageConverter" />
<bean
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
</bean>
</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>

修改Spring配置文件的xsd

修改Spring使用的quartz

<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.2.2</version>
</dependency>

同时修改quartz的配置文件：

<bean id="lctWorkTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail">
<bean class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<!-- 调用的类 -->
<property name="targetObject">
<ref bean="pushMessageWork" />
</property>
<!-- 调用类中的方法 -->
<property name="targetMethod">
<value>work</value>
</property>
</bean>
</property>
<!-- cron表达式 -->
<property name="cronExpression">
<value>0/30 * * * * ?</value>
</property>
</bean>

<!-- 总管理类 如果将lazy-init='false'那么容器启动就会执行调度程序 -->
<bean id="startQuertz" lazy-init="false" autowire="no"
class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="lctWorkTrigger" />
</list>
</property>
</bean>
