基本上，Spring 3.x版本最多Java-7仅支持。如果要迁移到Java-8，则应使用Spring 4.x版本。
However some spring release notes says that the Spring framework 3.2.x will support deployment on JDK 8 runtimes for applications compiled against JDK 7 (with -target 1.7) or earlier. Note that it won’t support JDK 8’s bytepre format (-target 1.8, as needed for lambdas); please upgrade to Spring framework 4.0 for that purpose.
