spring3.2与jdk1.8不兼容问题

JDK1.8 + spring 3.2 启动项目报错
DispatcherServlet - Context initialization failedjava.lang.IllegalArgumentException
javax.servlet.ServletException: Servlet.init() for servlet rootServlet threw exception

这是因为jdk1.8与spring3.2版本不兼容
将jdk版本降为1.7 或者 使用Spring4
如果使用spring4 则需要引入一下依赖
<dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-context</artifactId>   <version>4.3.9.RELEASE</version>   <exclusions>      <!-- Exclude Commons Logging in favor of SLF4j -->      <exclusion>         <groupId>commons-logging</groupId>         <artifactId>commons-logging</artifactId>      </exclusion>   </exclusions></dependency><dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-webmvc</artifactId>
   <version>4.3.9.RELEASE</version>
</dependency>

如果没有此依赖会出现报错为

java.lang.IllegalArgumentException: No converter found for return value of type: class xxxxxxx

需要引入以下：

<dependency>   <groupId>com.fasterxml.jackson.core</groupId>   <artifactId>jackson-core</artifactId>   <version>2.8.8</version></dependency><dependency>   <groupId>com.fasterxml.jackson.core</groupId>   <artifactId>jackson-databind</artifactId>   <version>2.8.8</version></dependency>
