• 04.shiro会话管理

    目录

    1.会话管理

    2.ehcache.xml的配置文件

    3.授权使用缓存

    1.会话管理

    在shiro里面新建一个类ShiroSessionListener 实现SessionListener3个方法

    1. package com.hz.ssm.shiro;
    2.  
    3. import org.apache.shiro.session.Session;
    4. import org.apache.shiro.session.SessionListener;
    5.  
    6. /**
    7.  * @author黄仲
    8.  * @site www.Hz.com
    9.  * @company 公司
    10.  * @create 2022-08-29 8:31
    11.  */
    12. public class ShiroSessionListener implements SessionListener {
    13.     @Override
    14.     public void onStart(Session session) {
    15.         System.out.println("ShiroSessionListener.onstart..."+session.getId());
    16.     }
    17.  
    18.     @Override
    19.     public void onStop(Session session) {
    20.         System.out.println("ShiroSessionListener.onStop..."+session.getId());
    21.     }
    22.  
    23.     @Override
    24.     public void onExpiration(Session session) {
    25.         System.out.println("ShiroSessionListener.onExpiration..."+session.getId());
    26.     }
    27. }
    28.

    然后到shiro.xml里面配置  稍微修改

    2.ehcache.xml的配置文件

    在resources中放入ehcache.xml

    1. "1.0" encoding="UTF-8"?>
    2. <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    3.          xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"
    4.          updateCheck="false">
    5.     
    6.     
    7.     
    8.     <diskStore path="D://xxx"/>
    9.  
    10.  
    11.     
    12.     
    13.     
    14.     
    15.     
    16.     
    17.     
    18.     
    19.     
    20.     
    21.     
    22.     <defaultCache eternal="false" maxElementsInMemory="1000" overflowToDisk="false" diskPersistent="false"
    23.                   timeToIdleSeconds="0" timeToLiveSeconds="600" memoryStoreEvictionPolicy="LRU"/>
    24.  
    25.  
    26.     
    27.     <cache name="com.javaxl.one.entity.User" eternal="false" maxElementsInMemory="100"
    28.            overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="0"
    29.            timeToLiveSeconds="300" memoryStoreEvictionPolicy="LRU"/>
    30. ehcache>

    3.授权使用缓存

    在项目中创建一个新的包ehcache，在里面创建3个类EhcacheDemo1，EhcacheUtil，EhcacheDemo2

    代码分别是EhcacheDemo1

    1. package com.hz.ssm.ehcache;
    2.  
    3. import java.util.HashMap;
    4. import java.util.Map;
    5.  
    6. /**
    7.  * @author黄仲
    8.  * @site www.Hz.com
    9.  * @company 公司
    10.  * @create 2022-08-29 9:58
    11.  */
    12. public class EhcacheDemo1 {
    13.         static Map<String,Object> cache=new HashMap<String,Object>();
    14.         static  Object getValue(String key){
    15.             Object value=cache.get(key);
    16.             if(value == null){
    17.                 System.out.println("hello zs");
    18.                 cache.put(key,new String[]{"zs"});
    19.                 return  cache.get(key);
    20.             }
    21.             return  value;
    22.         }
    23.  
    24.     public static void main(String[] args) {
    25.         System.out.println(getValue("sname"));
    26.         System.out.println(getValue("sname"));
    27.     }
    28. }
    29.

    EhcacheUtil

    1. package com.hz.ssm.ehcache;
    2.  
    3. import net.sf.ehcache.Cache;
    4. import net.sf.ehcache.CacheManager;
    5. import net.sf.ehcache.Element;
    6.  
    7. import java.io.InputStream;
    8.  
    9. public class EhcacheUtil {
    10.  
    11.     private static CacheManager cacheManager;
    12.  
    13.     static {
    14.         try {
    15.             InputStream is = EhcacheUtil.class.getResourceAsStream("/ehcache.xml");
    16.             cacheManager = CacheManager.create(is);
    17.         } catch (Exception e) {
    18.             throw new RuntimeException(e);
    19.         }
    20.     }
    21.  
    22.     private EhcacheUtil() {
    23.     }
    24.  
    25.     public static void put(String cacheName, Object key, Object value) {
    26.         Cache cache = cacheManager.getCache(cacheName);
    27.         if (null == cache) {
    28.             //以默认配置添加一个名叫cacheName的Cache
    29.             cacheManager.addCache(cacheName);
    30.             cache = cacheManager.getCache(cacheName);
    31.         }
    32.         cache.put(new Element(key, value));
    33.     }
    34.  
    35.  
    36.     public static Object get(String cacheName, Object key) {
    37.         Cache cache = cacheManager.getCache(cacheName);
    38.         if (null == cache) {
    39.             //以默认配置添加一个名叫cacheName的Cache
    40.             cacheManager.addCache(cacheName);
    41.             cache = cacheManager.getCache(cacheName);
    42.         }
    43.         Element element = cache.get(key);
    44.         return null == element ? null : element.getValue();
    45.     }
    46.  
    47.     public static void remove(String cacheName, Object key) {
    48.         Cache cache = cacheManager.getCache(cacheName);
    49.         cache.remove(key);
    50.     }
    51. }
    52.

    EhcacheDemo2

    1. package com.hz.ssm.ehcache;
    2.  
    3. /**
    4.  * @author黄仲
    5.  * @site www.Hz.com
    6.  * @company 公司
    7.  * @create 2022-08-29 10:20
    8.  */
    9. public class EhcacheDemo2 {
    10.     public static void main(String[] args) {
    11.         System.out.println(System.getProperty("java.io.tmpdir"));
    12. //		EhcacheUtil.put("com.javaxl.four.entity.Book", 11, "zhangsan");
    13. //		System.out.println(EhcacheUtil.get("com.javaxl.four.entity.Book", 11));
    14.  
    15.         EhcacheUtil.put("com.javaxl.one.entity.User", 11, "zhangsan");
    16.         System.out.println(EhcacheUtil.get("com.javaxl.one.entity.User", 11));
    17.  
    18.     }
    19.  
    20. }

    要导入pom依赖
