因： 这个错误主要是因为action的参数标注默认是debug级别，比如

@RequestMapping(value = "/login")
public ModelAndView login(String userName, String password, HttpServletRequest request) {
……

此时userName的级别时debug级别，而在linux、或者anbt下编译时是忽略了这些标注，导致请求时就会找不到userName的参数。 解决方法：

1. 修改参数的写法，比如修改为

@RequestMapping(value = "/login")
public ModelAndView login(@RequestParam("userName") String userName,
    @RequestParam("password") String password, HttpServletRequest request) {
	……

2.修改编译脚本（添加 debug="true"）

    <target name="compile" depends="clean">
        <javac source="${javaVersion}" target="${javaVersion}" srcdir="${basedir}" destdir="${basedir}/build" debug="true" includeantruntime="false">
        	<compilerarg line="-encoding UTF-8" />
        	<classpath refid="project.lib"></classpath>
        </javac>
    </target>
