web.xml文件配置
第一点，注意配置版本为3.0版本,
Servlet3.0规范中的<tracking-mode>允许你定义JSESSIONID是存储在cookie中还是URL参数中。如果会话ID存储在URL中，那么它可能会被无意的存储在多个地方，包括浏览器历史、代理服务器日志、引用日志和web日志等。暴露了会话ID使得网站被session劫持***的几率大增。然而，确保JSESSIONID被存储在cookie中

在使用shiro之后，shiro的重定向跳转，默认是带有JSESSIONID的
附上ShiroHttpServletResponse源码
@Override
public String encodeRedirectURL(String url){
/** 下面是ShiroHttpServletResponse源码，重写shiro的encodeRedirectURL方法，把url路径里的JSESSIONID去掉 **/
if (isEncodeable(toAbsolute(url))) {
return toEncoded(url, request.getSession().getId());
} else {
return url;
}
return url;
}上面是此类第一个方法，下面是此类第二个方法
@Override
protected String toEncoded(String url, String sessionId) {
if ((url == null) || (sessionId == null))
return (url);
String path = url;
String query = "";
String anchor = "";
int question = url.indexOf('?');
if (question >= 0) {
path = url.substring(0, question);
query = url.substring(question);
}
int pound = path.indexOf('#');
if (pound >= 0) {
anchor = path.substring(pound);
path = path.substring(0, pound);
}
StringBuilder sb = new StringBuilder(path);
/** 下面是ShiroHttpServletResponse源码，重写shiro的toEncoded方法使其不拼接JSESSIONID **/
if (sb.length() > 0) { // session id param can't be first.
sb.append(";");
sb.append(DEFAULT_SESSION_ID_PARAMETER_NAME);
sb.append("=");
sb.append(sessionId);
}
sb.append(anchor);
sb.append(query);
return (sb.toString());
}由此我们知道shiro第一次访问重定向的时候会带有JSESSIONID=xxxxxxxxxxxx
那么解决方案如下:
新建MyShiroHttpServletResponse继承ShiroHttpServletResponse
重写其方法encodeRedirectURL和toEncoded
package com.uu.back.util;
import org.apache.shiro.web.servlet.ShiroHttpServletRequest;
import org.apache.shiro.web.servlet.ShiroHttpServletResponse;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletResponse;
/**
* Created by Alex on 2016/9/26.
*/
public class MyShiroHttpServletResponse extends ShiroHttpServletResponse {
public MyShiroHttpServletResponse(HttpServletResponse wrapped, ServletContext context, ShiroHttpServletRequest request) {
super(wrapped, context, request);
}
@Override
public String encodeRedirectURL(String url){
/** 下面是ShiroHttpServletResponse源码，重写shiro的encodeRedirectURL方法，把url路径里的JSESSIONID去掉 **/
// if (isEncodeable(toAbsolute(url))) {
// return toEncoded(url, request.getSession().getId());
// } else {
// return url;
// }
return url;
}
@Override
protected String toEncoded(String url, String sessionId) {
if ((url == null) || (sessionId == null))
return (url);
String path = url;
String query = "";
String anchor = "";
int question = url.indexOf('?');
if (question >= 0) {
path = url.substring(0, question);
query = url.substring(question);
}
int pound = path.indexOf('#');
if (pound >= 0) {
anchor = path.substring(pound);
path = path.substring(0, pound);
}
StringBuilder sb = new StringBuilder(path);
/** 下面是ShiroHttpServletResponse源码，重写shiro的toEncoded方法使其不拼接JSESSIONID **/
// if (sb.length() > 0) { // session id param can't be first.
// sb.append(";");
// sb.append(DEFAULT_SESSION_ID_PARAMETER_NAME);
// sb.append("=");
// sb.append(sessionId);
// }
sb.append(anchor);
sb.append(query);
return (sb.toString());
}
}新建MySpringShiroFilter继承AbstractShiroFilter
package com.uu.back.util;
import org.apache.shiro.web.filter.mgt.FilterChainResolver;
import org.apache.shiro.web.mgt.WebSecurityManager;
import org.apache.shiro.web.servlet.AbstractShiroFilter;
import org.apache.shiro.web.servlet.ShiroHttpServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletResponse;
/**
* Created by Alex on 2016/9/26.
*/
public class MySpringShiroFilter extends AbstractShiroFilter {
protected MySpringShiroFilter(WebSecurityManager webSecurityManager, FilterChainResolver resolver) {
super();
if (webSecurityManager == null) {
throw new IllegalArgumentException("WebSecurityManager property cannot be null.");
}
setSecurityManager(webSecurityManager);
if (resolver != null) {
setFilterChainResolver(resolver);
}
}
@Override
protected ServletResponse wrapServletResponse(HttpServletResponse orig, ShiroHttpServletRequest request) {
return new MyShiroHttpServletResponse(orig, getServletContext(), request);
}
}新建MyShiroFilterFactoryBean继承ShiroFilterFactoryBean
package com.uu.back.util;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.filter.mgt.FilterChainManager;
import org.apache.shiro.web.filter.mgt.PathMatchingFilterChainResolver;
import org.apache.shiro.web.mgt.WebSecurityManager;
import org.apache.shiro.web.servlet.AbstractShiroFilter;
import org.springframework.beans.factory.BeanInitializationException;
/**
* Created by Alex on 2016/9/26.
*/
public class MyShiroFilterFactoryBean extends ShiroFilterFactoryBean {
@Override
public Class getObjectType() {
return MySpringShiroFilter.class;
}
@Override
protected AbstractShiroFilter createInstance() throws Exception {
SecurityManager securityManager = getSecurityManager();
if (securityManager == null) {
String msg = "SecurityManager property must be set.";
throw new BeanInitializationException(msg);
}
if (!(securityManager instanceof WebSecurityManager)) {
String msg = "The security manager does not implement the WebSecurityManager interface.";
throw new BeanInitializationException(msg);
}
FilterChainManager manager = createFilterChainManager();
PathMatchingFilterChainResolver chainResolver = new PathMatchingFilterChainResolver();
chainResolver.setFilterChainManager(manager);
return new MySpringShiroFilter((WebSecurityManager) securityManager, chainResolver);
}
}修改shiro的配置文件:
注释掉的就是原有的，现在我们不用原有的，使用我们自己写好的

<bean id="shiroFilter" class="com.uu.back.util.MyShiroFilterFactoryBean">
