shiro 默认获取shiro.ini的方式:
org.apache.shiro.web.env.EnvironmentLoaderListener中的
protected WebEnvironment createEnvironment(ServletContext sc)
{
Class clazz = determineWebEnvironmentClass(sc);
if(!org/apache/shiro/web/env/MutableWebEnvironment.isAssignableFrom(clazz))
throw new ConfigurationException((new StringBuilder()).append("Custom WebEnvironment class [").append(clazz.getName()).append("] is not of required type [").append(org/apache/shiro/web/env/WebEnvironment.getName()).append("]").toString());
String configLocations = sc.getInitParameter("shiroConfigLocations");
boolean configSpecified = StringUtils.hasText(configLocations);
if(configSpecified && !org/apache/shiro/config/ResourceConfigurable.isAssignableFrom(clazz))
{
String msg = (new StringBuilder()).append("WebEnvironment class [").append(clazz.getName()).append("] does not implement the ").append(org/apache/shiro/config/ResourceConfigurable.getName()).append("interface. This is required to accept any ").append("configured ").append("shiroConfigLocations").append("value(s).").toString();
throw new ConfigurationException(msg);
}
MutableWebEnvironment environment = (MutableWebEnvironment)ClassUtils.newInstance(clazz);
environment.setServletContext(sc);
if(configSpecified && (environment instanceof ResourceConfigurable))
((ResourceConfigurable)environment).setConfigLocations(configLocations);
customizeEnvironment(environment);
LifecycleUtils.init(environment);
return environment;
}通过调用LifecycleUtils.init(environment)
最终通过调用org.apache.shiro.web.env.IniWebEnvironment
public void init()
{
Ini ini = getIni();
String configLocations[] = getConfigLocations();
if(log.isWarnEnabled() && !CollectionUtils.isEmpty(ini) && configLocations != null && configLocations.length > 0)
log.warn("Explicit INI instance has been provided, but configuration locations have also been specified. The {} implementation does not currently support multiple Ini config, but this may be supported in the future. Only the INI instance will be used for configuration.", org/apache/shiro/web/env/IniWebEnvironment.getName());
if(CollectionUtils.isEmpty(ini))
{
log.debug("Checking any specified config locations.");
ini = getSpecifiedIni(configLocations);
}
if(CollectionUtils.isEmpty(ini))
{
log.debug("No INI instance or config locations specified. Trying default config locations.");
ini = getDefaultIni();
}
if(CollectionUtils.isEmpty(ini))
{
String msg = "Shiro INI configuration was either not found or discovered to be empty/unconfigured.";
throw new ConfigurationException(msg);
} else
{
setIni(ini);
configure();
return;
}
}
1.显示配置路径：
protected Ini getSpecifiedIni(String configLocations[])
throws ConfigurationException
{
Ini ini = null;
if(configLocations != null && configLocations.length > 0)
{
if(configLocations.length > 1)
log.warn("More than one Shiro .ini config location has been specified. Only the first will be used for configuration as the {} implementation does not currently support multiple files. This may be supported in the future however.", org/apache/shiro/web/env/IniWebEnvironment.getName());
ini = createIni(configLocations[0], true);
}
return ini;
}2.默认配置的路径:
protected Ini getDefaultIni()
{
Ini ini = null;
String configLocations[] = getDefaultConfigLocations();
if(configLocations != null)
{
String arr$[] = configLocations;
int len$ = arr$.length;
int i$ = 0;
do
{
if(i$ >= len$)
break;
String location = arr$[i$];
ini = createIni(location, false);
if(!CollectionUtils.isEmpty(ini))
{
log.debug("Discovered non-empty INI configuration at location ‘{}‘. Using for configuration.", location);
break;
}
i$++;
} while(true);
}
return ini;
}
protected String[] getDefaultConfigLocations()
{
return (new String[] {
"/WEB-INF/shiro.ini", "classpath:shiro.ini"
});
}
protected Ini createIni(String configLocation, boolean required)
throws ConfigurationException
{
Ini ini = null;
if(configLocation != null)
ini = convertPathToIni(configLocation, required);
if(required && CollectionUtils.isEmpty(ini))
{
String msg = (new StringBuilder()).append("Required configuration location ‘").append(configLocation).append("‘ does not exist or did not ").append("contain any INI configuration.").toString();
throw new ConfigurationException(msg);
} else
{
return ini;
}
}
private Ini convertPathToIni(String path, boolean required)
{
Ini ini = null;
if(StringUtils.hasText(path))
{
InputStream is = null;
if(!ResourceUtils.hasResourcePrefix(path))
is = getServletContextResourceStream(path);
else
try
{
is = ResourceUtils.getInputStreamForPath(path);
}
catch(IOException e)
{
if(required)
throw new ConfigurationException(e);
if(log.isDebugEnabled())
log.debug((new StringBuilder()).append("Unable to load optional path ‘").append(path).append("‘.").toString(), e);
}
if(is != null)
{
ini = new Ini();
ini.load(is);
} else
if(required)
throw new ConfigurationException((new StringBuilder()).append("Unable to load resource path ‘").append(path).append("‘").toString());
}
return ini;
}
private InputStream getServletContextResourceStream(String path)
{
InputStream is = null;
path = WebUtils.normalize(path);
ServletContext sc = getServletContext();
if(sc != null)
is = sc.getResourceAsStream(path);
return is;
