关于spring java.lang.IllegalArgumentException: Name for argument type [java.lang.String] 的错误

况描述：

 web工程在windows环境eclipse下编译部署没有问题，系统升级时需要运维从Git取相应的源码并编译部署到线上机器，部署启动正常没有错误，当访问业务的action时报错，如下。

错误如下

java.lang.IllegalArgumentException: Name for argument type [java.lang.String]
not available, and parameter name information not found in class file either.

原因：

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 = "/security/login", method = RequestMethod.POST)
public ModelAndView login(@RequestParam String userName, @RequestParam String password, 
    HttpServletRequest request) {

此时userName的级别时debug级别，而在linux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 = "/security/login", method = RequestMethod.POST) 
public ModelAndView login(@RequestParam("userName") String userName, 
    @RequestParam("password") String password,  
    HttpServletRequest request) { 
    ......................

2.修改编译脚本

SRC=$(find ./java/* | grep java$)
javac -g -d ./classes  $SRC -encoding utf-8

增加 -g 参数，即编译时生成所有debug的信息。

为了这个问题费了很大劲，主要参考了了

1.http://stackoverflow.com/questions/2622018/compile-classfile-issue-in-spring-3   这个主要是因为ant编译导致类似的问题。

2.  http://stackoverflow.com/questions/10305592/error-class-names-are-only-accepted-if-annotation-processing-is-explicitly-req    一开始src的写法有些问题，改为上面的写法便可。
