小编Dav*_*ulz的帖子

我看到 boolean 的显式强制转换语法在语法上(boolean)是合法的，但我想不出它的用途。相应的 Boolean 对象——或者更确切地说是在 boolean 和 Boolean 之间来回转换——由自动装箱处理。所以它看起来像是编译器的无用语言工件。是否有我缺少的功能场景？

我在控制器的方法中有几个SYSOUT,它们出现在控制台日志中......验证我所有的@RequestMapping都按预期运行.环境bean的@Autowiring也在工作(SYSOUT也正确显示).

但是,方法的返回(我使用返回String类型的方法)仅导致404s.找不到*.jsps.项目正在使用Maven; IDE是eclipse kepler,FWIW.

我的ViewResolver是标准的.看不到断开连接.
