spring boot爬坑之旅途--数据源配置整合druid(2)

项目结构如下：

启动入口：

import org.springframework.jmx.support.RegistrationPolicy;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import com.github.tobato.fastdfs.FdfsClientConfig;
//解决jmx重复注册bean的问题
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)
//整合fastdsf
@Import(FdfsClientConfig.class)
//启动入口
@SpringBootApplication
//配置servlet

//事务
@EnableTransactionManagement
public class BlogStart {
	public static void main(String[] args) {
		SpringApplication.run(BlogStart.class, args);
	}
}

1.使用druid进行数据库访问

1.1基于resource.properties配置初始化数据源属性

package com.zm.blog.config.druid;

import java.sql.SQLException;

import javax.sql.DataSource;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.aop.Advisor;
import org.springframework.aop.support.DefaultPointcutAdvisor;
import org.springframework.aop.support.JdkRegexpMethodPointcut;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.spring.stat.DruidStatInterceptor;

@Configuration
public class DruidConfig {
	private static final Logger LOGGER = LoggerFactory.getLogger(DruidConfig.class);

	@Value("${spring.datasource.driverClassName}")
	private String driverClassName;
	@Value("${spring.datasource.url}")
	private String url;
	@Value("${spring.datasource.username}")
	private String username;
	@Value("${spring.datasource.password}")
	private String password;
	@Value("${spring.datasource.initialSize}")
	private int initialSize;
	@Value("${spring.datasource.minIdle}")
	private int minIdle;
	@Value("${spring.datasource.maxActive}")
	private int maxActive;
	@Value("${spring.datasource.maxWait}")
	private int maxWait;
	@Value("${spring.datasource.validationQuery}")
	private String validationQuery;
	@Value("${spring.datasource.testOnBorrow}")
	private boolean testOnBorrow;
	@Value("${spring.datasource.testOnReturn}")
	private boolean testOnReturn;
	@Value("${spring.datasource.testWhileIdle}")
	private boolean testWhileIdle;
	@Value("${spring.datasource.timeBetweenEvictionRunsMillis}")
	private int timeBetweenEvictionRunsMillis;
	@Value("${spring.datasource.minEvictableIdleTimeMillis}")
	private int minEvictableIdleTimeMillis;
	@Value("${spring.datasource.removeAbandoned}")
	private boolean removeAbandoned;
	@Value("${spring.datasource.removeAbandonedTimeout}")
	private int removeAbandonedTimeout;
	@Value("${spring.datasource.logAbandoned}")
	private boolean logAbandoned;
	@Value("${spring.datasource.filters}")
	private String filters;
	@Value("${spring.datasource.poolPreparedStatements}")
	private boolean poolPreparedStatements;
	@Value("${spring.datasource.maxPoolPreparedStatementPerConnectionSize}")
	private int maxPoolPreparedStatementPerConnectionSize;

	// 添加aop的advice
	@Bean
	public DruidStatInterceptor druidStatInterceptor() {
		DruidStatInterceptor druidStatInterceptor = new DruidStatInterceptor();
		return druidStatInterceptor;
	}

	// 添加aop的pointcut
	@Bean
	public JdkRegexpMethodPointcut jdkRegexpMethodPointcut() {
		JdkRegexpMethodPointcut jdkRegexpMethodPointcut = new JdkRegexpMethodPointcut();
		jdkRegexpMethodPointcut.setPatterns(new String[] {"com.zm.blog.uib.service.*","com.zm.blog.uib.controller.*"});
		return jdkRegexpMethodPointcut;
	}

	// 设置默认的aop配置对应的是原来的<aop:advisor>
	@Bean
	public Advisor druidAdvisor() {
		DefaultPointcutAdvisor defaultPointcutAdvisor = new DefaultPointcutAdvisor();
		defaultPointcutAdvisor.setPointcut(jdkRegexpMethodPointcut());
		defaultPointcutAdvisor.setAdvice(druidStatInterceptor());
		return defaultPointcutAdvisor;
	}

	@Bean
	@Primary
	public DataSource dataSource() {
		DruidDataSource datasource = new DruidDataSource();

		datasource.setDriverClassName(driverClassName);
		datasource.setUrl(url);
		datasource.setUsername(username);
		datasource.setPassword(password);
		// 其它配置
		datasource.setInitialSize(initialSize);
		datasource.setMinIdle(minIdle);
		datasource.setMaxActive(maxActive);
		datasource.setMaxWait(maxWait);
		datasource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);
		datasource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);
		datasource.setValidationQuery(validationQuery);
		datasource.setTestWhileIdle(testWhileIdle);
		datasource.setTestOnBorrow(testOnBorrow);
		datasource.setTestOnReturn(testOnReturn);
		datasource.setPoolPreparedStatements(poolPreparedStatements);
		datasource.setMaxPoolPreparedStatementPerConnectionSize(maxPoolPreparedStatementPerConnectionSize);

		try {
			datasource.setFilters(filters);
		} catch (SQLException e) {
			LOGGER.error("druid configuration initialization filter", e);
		}
		return datasource;
	}
}

1.2配置使用druid使用的过滤器

package com.zm.blog.config.druid;

import javax.servlet.annotation.WebFilter;
import javax.servlet.annotation.WebInitParam;

import com.alibaba.druid.support.http.WebStatFilter;

@WebFilter(filterName="druidWebStatFilter",urlPatterns="/*",
initParams={
    @WebInitParam(name="exclusions",value="*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*")// 忽略资源
})
public class DruidStatFilter extends WebStatFilter{
	
}

1.3 servlet配置

package com.zm.blog.config.druid;

import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;

import com.alibaba.druid.support.http.StatViewServlet;

@WebServlet(urlPatterns = "/druid/*", 
initParams={
        //@WebInitParam(name="allow",value="127.0.0.1"),// IP白名单 (没有配置或者为空，则允许所有访问)
        //@WebInitParam(name="deny",value="192.168.16.111"),// IP黑名单 (存在共同时，deny优先于allow)
        @WebInitParam(name="loginUsername",value="admin"),// 用户名
        @WebInitParam(name="loginPassword",value="isadmin"),// 密码
        @WebInitParam(name="resetEnable",value="false")// 禁用HTML页面上的“Reset All”功能
})
public class DruidStatViewServlet extends StatViewServlet {

	private static final long serialVersionUID = 1L;

}

备注：下文的举出配置都是基于resource.properties文件
