权限管理系统4—集成Druid数据源

Druid是Java语言中最好的数据库连接池。Druid能够提供强大的监控和扩展功能。

1.导包

<!-- druid --><dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>1.1.10</version></dependency><!-- log4j --><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency>

2.添加配置

修改application.yml

spring:datasource:name: druidDataSourcetype: com.alibaba.druid.pool.DruidDataSourcedruid:driver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://localhost:3306/mango?useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTCusername: rootpassword: 101800filters: stat,wall,log4j,configmax-active: 100initial-size: 1max-wait: 60000min-idle: 1time-between-eviction-runs-millis: 60000min-evictable-idle-time-millis: 300000validation-query: select 'x'test-while-idle: truetest-on-borrow: falsetest-on-return: falsepool-prepared-statements: truemax-open-prepared-statements: 50max-pool-prepared-statement-per-connection-size: 20

添加配置类

package com.chq.mango.config;import org.springframework.boot.context.properties.ConfigurationProperties;/*** 数据源属性*/
@ConfigurationProperties(prefix = "spring.datasource.druid")
public class DruidDataSourceProperties {// jdbcprivate String driverClassName;private String url;private String username;private String password;// jdbc connection poolprivate int initialSize;private int minIdle;private int maxActive = 100;private long maxWait;private long timeBetweenEvictionRunsMillis;private long minEvictableIdleTimeMillis;private String validationQuery;private boolean testWhileIdle;private boolean testOnBorrow;private boolean testOnReturn;private boolean poolPreparedStatements;private int maxPoolPreparedStatementPerConnectionSize;// filterprivate String filters;public int getInitialSize() {return initialSize;}public void setInitialSize(int initialSize) {this.initialSize = initialSize;}public int getMinIdle() {return minIdle;}public void setMinIdle(int minIdle) {this.minIdle = minIdle;}public int getMaxActive() {return maxActive;}public void setMaxActive(int maxActive) {this.maxActive = maxActive;}public long getMaxWait() {return maxWait;}public void setMaxWait(long maxWait) {this.maxWait = maxWait;}public long getTimeBetweenEvictionRunsMillis() {return timeBetweenEvictionRunsMillis;}public void setTimeBetweenEvictionRunsMillis(long timeBetweenEvictionRunsMillis) {this.timeBetweenEvictionRunsMillis = timeBetweenEvictionRunsMillis;}public long getMinEvictableIdleTimeMillis() {return minEvictableIdleTimeMillis;}public void setMinEvictableIdleTimeMillis(long minEvictableIdleTimeMillis) {this.minEvictableIdleTimeMillis = minEvictableIdleTimeMillis;}public String getValidationQuery() {return validationQuery;}public void setValidationQuery(String validationQuery) {this.validationQuery = validationQuery;}public boolean isTestWhileIdle() {return testWhileIdle;}public void setTestWhileIdle(boolean testWhileIdle) {this.testWhileIdle = testWhileIdle;}public boolean isTestOnBorrow() {return testOnBorrow;}public void setTestOnBorrow(boolean testOnBorrow) {this.testOnBorrow = testOnBorrow;}public boolean isTestOnReturn() {return testOnReturn;}public void setTestOnReturn(boolean testOnReturn) {this.testOnReturn = testOnReturn;}public boolean isPoolPreparedStatements() {return poolPreparedStatements;}public void setPoolPreparedStatements(boolean poolPreparedStatements) {this.poolPreparedStatements = poolPreparedStatements;}public int getMaxPoolPreparedStatementPerConnectionSize() {return maxPoolPreparedStatementPerConnectionSize;}public void setMaxPoolPreparedStatementPerConnectionSize(int maxPoolPreparedStatementPerConnectionSize) {this.maxPoolPreparedStatementPerConnectionSize = maxPoolPreparedStatementPerConnectionSize;}public String getFilters() {return filters;}public void setFilters(String filters) {this.filters = filters;}public String getDriverClassName() {return driverClassName;}public void setDriverClassName(String driverClassName) {this.driverClassName = driverClassName;}public String getUrl() {return url;}public void setUrl(String url) {this.url = url;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}}

3.配置Servlet和Filter

package com.chq.mango.config;import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import javax.servlet.Filter;
import javax.servlet.Servlet;
import javax.sql.DataSource;
import java.sql.SQLException;/*** Druid数据源配置*/
@Configuration
@EnableConfigurationProperties({DruidDataSourceProperties.class})
public class DruidConfig {@Autowiredprivate DruidDataSourceProperties properties;@Bean@ConditionalOnMissingBeanpublic DataSource druidDataSource() {DruidDataSource druidDataSource = new DruidDataSource();druidDataSource.setDriverClassName(properties.getDriverClassName());druidDataSource.setUrl(properties.getUrl());druidDataSource.setUsername(properties.getUsername());druidDataSource.setPassword(properties.getPassword());druidDataSource.setInitialSize(properties.getInitialSize());druidDataSource.setMinIdle(properties.getMinIdle());druidDataSource.setMaxActive(properties.getMaxActive());druidDataSource.setMaxWait(properties.getMaxWait());druidDataSource.setTimeBetweenEvictionRunsMillis(properties.getTimeBetweenEvictionRunsMillis());druidDataSource.setMinEvictableIdleTimeMillis(properties.getMinEvictableIdleTimeMillis());druidDataSource.setValidationQuery(properties.getValidationQuery());druidDataSource.setTestWhileIdle(properties.isTestWhileIdle());druidDataSource.setTestOnBorrow(properties.isTestOnBorrow());druidDataSource.setTestOnReturn(properties.isTestOnReturn());druidDataSource.setPoolPreparedStatements(properties.isPoolPreparedStatements());druidDataSource.setMaxPoolPreparedStatementPerConnectionSize(properties.getMaxPoolPreparedStatementPerConnectionSize());try {druidDataSource.setFilters(properties.getFilters());druidDataSource.init();} catch (SQLException e) {e.printStackTrace();}return druidDataSource;}/*** 注册Servlet信息， 配置监控视图** @return*/@Bean@ConditionalOnMissingBeanpublic ServletRegistrationBean<Servlet> druidServlet() {ServletRegistrationBean<Servlet> servletRegistrationBean = new ServletRegistrationBean<Servlet>(new StatViewServlet(), "/druid/*");//白名单：
//        servletRegistrationBean.addInitParameter("allow","127.0.0.1,139.196.87.48");//IP黑名单 (存在共同时，deny优先于allow) : 如果满足deny的话提示:Sorry, you are not permitted to view this page.servletRegistrationBean.addInitParameter("deny","192.168.1.119");//登录查看信息的账号密码, 用于登录Druid监控后台servletRegistrationBean.addInitParameter("loginUsername", "admin");servletRegistrationBean.addInitParameter("loginPassword", "admin");//是否能够重置数据.servletRegistrationBean.addInitParameter("resetEnable", "true");return servletRegistrationBean;}/*** 注册Filter信息, 监控拦截器** @return*/@Bean@ConditionalOnMissingBeanpublic FilterRegistrationBean<Filter> filterRegistrationBean() {FilterRegistrationBean<Filter> filterRegistrationBean = new FilterRegistrationBean<Filter>();filterRegistrationBean.setFilter(new WebStatFilter());filterRegistrationBean.addUrlPatterns("/*");filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");return filterRegistrationBean;}
}

4.编译运行

登陆+密码都admin，访问：http://localhost:8001/druid/login.html
