1.导入web项目,创建authentication模块,并修改pom.xml文件
2.将profiles文件粘贴到authentication模块中,profiles文件夹里面有两个文件database.properties和redis.properties文件
修改database.properties中的数据库连接属性(用户名,密码,数据库名称等),修改redis.properties文件redis属性(可能修改主机地址,连接密码)
3.创建server-common模块,配置相应pom文件,并且在父pom文件中定义此模块,然后在authentication模块中引用此模块,在server-common模块的src/main/com.yootk.server.config/粘贴SpringDataRedisConfig.class文件
package com.yootk.server.config; import org.apache.commons.pool2.impl.GenericObjectPoolConfig; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.PropertySource; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.connection.RedisPassword; import org.springframework.data.redis.connection.RedisStandaloneConfiguration; import org.springframework.data.redis.connection.lettuce.LettuceClientConfiguration; import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory; import org.springframework.data.redis.connection.lettuce.LettucePoolingClientConfiguration; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.JdkSerializationRedisSerializer; import org.springframework.data.redis.serializer.StringRedisSerializer; @Configuration @PropertySource("classpath:redis.properties") public class SpringDataRedisConfig { @Bean("redisConfiguration") public RedisStandaloneConfiguration getRedisConfiguration( @Value("${redis.host}") String hostName , @Value("${redis.port}") int port, @Value("${redis.auth}") String password, @Value("${redis.database}") int database ) { RedisStandaloneConfiguration configuration = new RedisStandaloneConfiguration() ; configuration.setHostName(hostName); // 设置Redis主机名称 configuration.setPort(port); // 设置Redis的访问端口 configuration.setPassword(RedisPassword.of(password)); // 设置密码 configuration.setDatabase(database); // 设置数据库索引 return configuration ; } @Bean("objectPoolConfig") public GenericObjectPoolConfig getObjectPoolConfig( @Value("${redis.pool.maxTotal}") int maxTotal , @Value("${redis.pool.maxIdle}") int maxIdle , @Value("${redis.pool.minIdle}") int minIdle , @Value("${redis.pool.testOnBorrow}") boolean testOnBorrow ) { GenericObjectPoolConfig poolConfig = new GenericObjectPoolConfig() ; poolConfig.setMaxTotal(maxTotal); poolConfig.setMaxIdle(maxIdle); poolConfig.setMinIdle(minIdle); poolConfig.setTestOnBorrow(testOnBorrow); return poolConfig ; } @Bean("lettuceClientConfiguration") public LettuceClientConfiguration getLettuceClientConfiguration( @Autowired GenericObjectPoolConfig poolConfig ) { // 创建Lettuce组件的连接池客户端配置对象 return LettucePoolingClientConfiguration.builder().poolConfig(poolConfig).build() ; } @Bean("redisConnectionFactory") public RedisConnectionFactory getConnectionFactory( @Autowired RedisStandaloneConfiguration redisConfiguration , @Autowired LettuceClientConfiguration lettuceClientConfiguration ) { LettuceConnectionFactory connectionFactory = new LettuceConnectionFactory(redisConfiguration,lettuceClientConfiguration) ; return connectionFactory ; } @Bean("redisTemplate") public RedisTemplate getRedisTempalate( @Autowired RedisConnectionFactory connectionFactory ) { RedisTemplate<Object,Object> redisTemplate = new RedisTemplate<>() ; redisTemplate.setConnectionFactory(connectionFactory); redisTemplate.setKeySerializer(new StringRedisSerializer()); // 数据的key通过字符串存储 redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer()); // 保存的value为对象 redisTemplate.setHashKeySerializer(new StringRedisSerializer()); // 数据的key通过字符串存储 redisTemplate.setHashValueSerializer(new JdkSerializationRedisSerializer()); // 保存的value为对象 return redisTemplate ; } }
4.在server-common模块的src/main/com.yootk.server.config/粘贴DatabaseConfig.class文件,写完之后spring-database.xml配置文件就没用了,删除掉它。
package com.yootk.server.config; import com.alibaba.druid.pool.DruidDataSource; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.PropertySource; import org.springframework.data.repository.NoRepositoryBean; import javax.sql.DataSource; import java.sql.SQLException; @Configuration @PropertySource("classpath:database.properties") public class DatabaseConfig { @Value("${db.druid.driverClassName}") private String driverClassName ; @Value("${db.druid.url}") private String url ; @Value("${db.druid.username}") private String username ; @Value("${db.druid.password}") private String password ; @Value("${db.druid.maxActive}") private int maxActive ; @Value("${db.druid.minIdle}") private int minIdle ; @Value("${db.druid.initialSize}") private int initialSize ; @Value("${db.druid.maxWait}") private long maxWait ; @Value("${db.druid.timeBetweenEvictionRunsMillis}") private long timeBetweenEvictionRunsMillis ; @Value("${db.druid.minEvictableIdleTimeMillis}") private long minEvictableIdleTimeMillis ; @Value("${db.druid.validationQuery}") private String validationQuery ; @Value("${db.druid.testWhileIdle}") private boolean testWhileIdle ; @Value("${db.druid.testOnBorrow}") private boolean testOnBorrow ; @Value("${db.druid.testOnReturn}") private boolean testOnReturn ; @Value("${db.druid.poolPreparedStatements}") private boolean poolPreparedStatements ; @Value("${db.druid.maxPoolPreparedStatementPerConnectionSize}") private int maxPoolPreparedStatementPerConnectionSize ; @Value("${db.druid.filters}") private String filters ; @Bean("dataSource") public DataSource getDruidDataSource() { DruidDataSource dataSource = new DruidDataSource() ; dataSource.setDriverClassName(this.driverClassName); dataSource.setUrl(this.url); dataSource.setUsername(this.username); dataSource.setPassword(this.password); dataSource.setMaxActive(this.maxActive); dataSource.setMinIdle(this.minIdle); dataSource.setInitialSize(this.initialSize); dataSource.setMaxWait(this.maxWait); dataSource.setTimeBetweenEvictionRunsMillis(this.timeBetweenEvictionRunsMillis); dataSource.setMinEvictableIdleTimeMillis(this.minEvictableIdleTimeMillis); dataSource.setValidationQuery(this.validationQuery); dataSource.setTestWhileIdle(this.testWhileIdle); dataSource.setTestOnBorrow(this.testOnBorrow); dataSource.setTestOnReturn(this.testOnReturn); dataSource.setPoolPreparedStatements(this.poolPreparedStatements); dataSource.setMaxPoolPreparedStatementPerConnectionSize(this.maxPoolPreparedStatementPerConnectionSize); try { dataSource.setFilters(this.filters); } catch (SQLException e) { e.printStackTrace(); } return dataSource ; } }
5.在server-common模块的src/main/com.yootk.server.cache目录下粘贴RedisCache.java文件
package com.yootk.server.cache; import org.springframework.cache.Cache; import org.springframework.cache.support.SimpleValueWrapper; import org.springframework.data.redis.core.RedisTemplate; import java.util.concurrent.Callable; public class RedisCache implements Cache { private RedisTemplate<String,Object> redisTemplate ; private String name ; // 缓存名称 // 此时进行的Redis缓存操作实现类型需要通过配置文件的形式完成 public void setRedisTemplate(RedisTemplate<String, Object> redisTemplate) { this.redisTemplate = redisTemplate; } public void setName(String name) { this.name = name; } @Override public String getName() { return this.name; } @Override public Object getNativeCache() { return this.redisTemplate; } @Override public ValueWrapper get(Object o) { Object result = this.redisTemplate.opsForValue().get(String.valueOf(o)) ; if (result != null) { // 已经查找到相应数据 return new SimpleValueWrapper(result) ; } return null; } @Override public <T> T get(Object o, Class<T> aClass) { Object result = this.redisTemplate.opsForValue().get(String.valueOf(o)) ; if (result != null) { // 已经查找到相应数据 return (T) result ; } return null; } @Override public <T> T get(Object o, Callable<T> callable) { return null; } @Override public void put(Object key, Object value) { this.redisTemplate.opsForValue().set(String.valueOf(key),value); } @Override public ValueWrapper putIfAbsent(Object key, Object value) { Object result = this.redisTemplate.opsForValue().get(String.valueOf(key)) ; if (result == null) { this.redisTemplate.opsForValue().set(String.valueOf(key),value); return new SimpleValueWrapper(value) ; } return new SimpleValueWrapper(result); } @Override public void evict(Object o) { this.redisTemplate.delete(String.valueOf(o)) ; } @Override public void clear() { this.redisTemplate.getConnectionFactory().getConnection().flushDb(); } }
