在NutzBoot中拆分Shiro.ini配置文件使 Urls 能够配置多个并和 main 配置分离
Nutzboot简介:html
NutzBoot为一个基于Nutz框架的微服务方案,如下简称NB!其他略...java
NB文档简介:http://www.nutzam.com/core/bo...web
简介:apache
首先关于Nutz以及NB,shiro等介绍以及微服务的概念在此略过,本文中介绍的方法基于Nutz框架,但实现思路和核心类应该能够在其余框架中通用.服务器
一.首先阐述一下研究这个东西的出发点.
一开始在NB中也是使用的shiro.ini配置文件完成对shiro的配置的,可是在实际开发过程当中发现,在配置微服务的过程当中,shiro文件须要配置或复制屡次,这里插一嘴咱们的实现方式,咱们服务的实现方式为,全部须要独立部署的服务器都会实现同一个基础服务器运行库,来完成通用配置等.app
在配置多个服务器的时候发现不一样服务器之间若是只使用一个shiro.ini配置文件会出现,[urls]配置下的url重复的状况,即例如先后台的/user/login接口,既是在NB的配置中配置不一样服务器上下文,也没法避免同一个shiro配置文件出现此问题框架
为了解决这个问题其实也想过将不一样服务的配置文件分离(固然这在NB结构中是能够实现的),可是出现shiro.ini中[main]等配置被复制屡次的状况,不美观也不利于修改.ide
二.解决思路
为了解决这个问题其实一开始想到的是经过NB中shiro-stater中已有的 shiro.ini.urls 配置解决(这个配置容许在其余一个文件中手写shiro urls 配置列表)微服务
后来发现这个配置没法和 shiro.ini配置文件一块儿使用(这个配置大概是给使用默认配置的同窗使用的)优化
而已有的shiro大部分配置都在shiro.ini配置文件中,不太可能写成代码形式,只能另寻他法
最后通过几经寻找,最终肯定能解决这个问题的方法是(也修改了不少次,这里说了最后两种)
1.复制shiro-starter源码,利用其中已有的重写shiro的 EnvironmentLoaderListener的类,以和以前部分相同的逻辑初始化Shiro.
2.修改上述Listener在传入Environment处作修改(此处省略了starter获取配置文件路径并传入的部分,以及配置非空部分),传入一个重写的Environment,这个重写的类中大部分实现逻辑是由 shiro处理源码IniWebEnvironment类复制过来的,用来完成 shiro.ini文件的配置加载.
3.修改重写类代码,使其能够获取到NB starter的配置(略,用来传入路径或urls),并修改源码中获取Filter的方法createFilterChainResolver()
在其建立Filter实例以前插入代码
ini.load(String);
源码:(此处检查了是否有 urls和filter配置)
// only create a resolver if the 'filters' or 'urls' sections are defined:
Ini.Section urls = ini.getSection(IniFilterChainResolverFactory.URLS);
Ini.Section filters = ini.getSection(IniFilterChainResolverFactory.FILTERS);
if (!CollectionUtils.isEmpty(urls) || !CollectionUtils.isEmpty(filters)) {
// either the urls section or the filters section was defined. Go ahead and create the resolver:
IniFilterChainResolverFactory factory = new IniFilterChainResolverFactory(ini, this.objects);
resolver = factory.getInstance();
}
修改后的代码(此处须要注意咱们逻辑中没有 filter配置,这里就没判断)
//urls为符合 ini语法的字符串 例如 /user/login = anon
String iniUrls = "[urls]\r\n" + urls;
ini.load(iniUrls);
// 此代码前,在此处ini会被加载成类
// ini对象在此方法以前就存在,this.object则由父类中负责
IniFilterChainResolverFactory factory = new IniFilterChainResolverFactory(ini, this.objects);
resolver = factory.getInstance();
这里须要注意在调用 ini.load后原文件中的 [urls] 配置会被覆盖,而当只有[urls] 但并无实际内容时并不会被覆盖(没试过空行,请注意)
4.在完成这段代码后发现代码很是难看,shiro urls被配置到了java文件中,为了不这个问题使用了NB-start直接带的配置方式以及已经存在的 shiro.ini.urls属性,将配置文件中的 urls传入代码中
因此在NB中就成了这样
//获取配置文件中urls
String urls = conf.get(ShiroEnvStarter.PROP_INIT_URLS, null);
//urls为符合 ini语法的字符串 例如 /user/login = anon
String iniUrls = "[urls]\r\n" + urls;
ini.load(iniUrls);
// 此代码前,在此处ini会被加载成类
// ini对象在此方法以前就存在,this.object则由父类中负责
IniFilterChainResolverFactory factory = new IniFilterChainResolverFactory(ini, this.objects);
resolver = factory.getInstance();
在NB的application.properties配置文件中写法为
shiro.ini.urls:
/unathenticated = anon
/user/login = anon
#end
这里还要手动@并感谢下 @wendal @nutzcn
以前并不知道application.properties中多行的写法
至此,整个在代码中覆盖 shiro urls 配置的思路基本就完成了,只剩下一些相似于非空判断参数获取的代码.在此实现下便可实现项目中Shiro main配置为统一文件,而urls配置为专用单独文件
以后要介绍的就是优化部分以及,完整代码
三.优化(彻底基于NB)
1.在使用中发现虽然如今 urls已经能够独立文件配置,但多行之间并不能够写注解(在NB层就不会读取完整),而且和 shiro.ini中语法并不彻底同样.
最后解决办法为:在项目中添加另外一个.ini的配置文件,并在项目中读取ini文件并使用 ini.load加载
2.在添加了ini配置文件后发现最好能够有一部分urls能够通用配置,另外一部分能够独立配置.
最后解决方式为:添加两个shiro-url.ini配置文件,并在代码中读取并拼接,在库服务中添加,一个ini文件,并在每一个独立的服务中添加彻底同路径和名称的文件,使用其打包时互相覆盖的特性,达到独立配置的目的,而另外一个不进行覆盖达到通用配置的目的.
而在NB中经过在 starter源码中添加新的配置达到url能够配置并传入的目的.
@PropDoc(value = "urls过滤清单ini文件1路径")
public static final String PROP_INIT_URLS_PATH1 = "shiro.ini.urls.path1";
@PropDoc(value = "urls过滤清单ini文件2路径")
public static final String PROP_INIT_URLS_PATH2 = "shiro.ini.urls.path2";
这里附上读取并拼接两个 ini的代码
private boolean loadIniPath1ANd2(Ini ini) {
String urlsAll = "";
String urls1 = readConfig(ShiroEnvStarter.PROP_INIT_URLS_PATH1);
String urls2 = readConfig(ShiroEnvStarter.PROP_INIT_URLS_PATH2);
urlsAll = urls1 + urls2;
if (!urlsAll.equals("")) {
String iniUrls = "[urls]\r\n" + urlsAll;
log.info("shiro ini urls ---> \r\n" + iniUrls);
// Ini ini = new Ini();
// ini.load(iniUrls);
// Ini.Section section = ini.getSection(Ini.DEFAULT_SECTION_NAME);
// Log.info(section.toString());
// 注意这个代码中这里load过一次了
ini.load(iniUrls);
// 此处验证了 ini并无全被覆盖,只覆盖了 加载的配置文件部分
// 若是新加载的内容中 只有 [main] 标签不会被覆盖,可是若是 [main]标签下有内容 则会覆盖以前的配置
// for (Entry<String, Ini.Section> entry : ini.entrySet()) {
// jline.internal.Log.info(entry.getKey());
// for (Entry<String, String> entryStr : entry.getValue().entrySet()) {
// jline.internal.Log.info(entryStr);
// }
// }
return true;
}
return false;
}
private String readConfig(String confPath) {
String urls1 = "";
try {
String path = conf.get(confPath, "").trim();
log.info("path:" + path);
if (path != null && appContext.getResourceLoader().has(path)) {
InputStream is = ResourceUtils.getInputStreamForPath("classpath:" + path);
if (is != null) {
urls1 = readIniFile(is);
}
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return urls1;
}
private String readIniFile(InputStream is) throws IOException {
// InputStreamReader reader =new InputStreamReader(new
// FileInputStream(file),"UTF-8");
InputStreamReader reader = new InputStreamReader(is);
BufferedReader br = new BufferedReader(reader);
StringBuffer sbf = new StringBuffer();
while (true) {
String str = br.readLine();
if (str != null) {
sbf.append(str).append("\r\n");
} else {
break;
}
}
br.close();
reader.close();
return sbf.toString();
}
固然代码中依旧有能够优化的地方,不过这里就先不写了,嘿嘿
不过至此已经达到能想到的最好的效果了,父子项目中 父项目配置 shiro main中验证和DB,Redis的大部分通用配置,以及全部通用的urls过滤,而子类能够添加新的urls配置,而且各个子项目中 shiro配置并不冲突.
至此整偏博客结束,若是其中有错误也请你们告诉我了~~
