spring boot druid quartz 整合 spring boot druid 配置

Spring boot 配置Druid环境的Demo——(Druid环境配置)

#话不多说直接走你

先看下项目基本结构，基本就是大差不差，无非名字不一样

1.首先是数据库表的建立

2.创建spring boot 项目

3.配置pom.xml

配置所需要的运行环境

<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>javax.servlet-api</artifactId>
			<scope>provided</scope>
		</dependency>

		<!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
		<!-- druid连接池 -->
		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>druid</artifactId>
			<version>1.1.16</version>
		</dependency>

		<!-- https://mvnrepository.com/artifact/log4j/log4j -->
		<!-- log4j日志 -->
		<dependency>
			<groupId>log4j</groupId>
			<artifactId>log4j</artifactId>
			<version>1.2.17</version>
		</dependency>

		<!-- https://mvnrepository.com/artifact/org.aspectj/aspectjweaver -->
		<dependency>
			<groupId>org.aspectj</groupId>
			<artifactId>aspectjweaver</artifactId>
			<version>1.9.2</version>
		</dependency>

4.配置application.properties

这个是基本的配置

#server
#端口设置，类似于tomcat的端口号这里**修改成了666不是8080**#
server.port=666
#端口编码设置
server.tomcat.uri-encoding=utf-8

#datasource
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver  #这个是高版本的mysql-connector-java 
spring.datasource.url=jdbc:mysql://localhost:3306/test?serverTimezone=UTC&characterEncoding=utf-8 ##这里需要设置时区
spring.datasource.username=root
spring.datasource.password=root

#mybatis
mybatis.type-aliases-package=com.mypack.entity
mybatis.mapper-locations=classpath:mapper/*.xml

# thymeleaf
#html的前缀后缀
spring.thymeleaf.prefix=classpath:/static/
spring.mvc.view.prefix=classpath:/static/
spring.thymeleaf.suffix=.html
#基本属性
spring.thymeleaf.servlet.content-type=text/html
spring.thymeleaf.cache=false
spring.thymeleaf.mode=HTML5

这个是Druid配置

##  druid配置  
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

# 初始化大小，最小，最大  
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
# 配置获取连接等待超时的时间  
spring.datasource.maxWait=60000
# 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒  
spring.datasource.timeBetweenEvictionRunsMillis=60000
# 配置一个连接在池中最小生存的时间，单位是毫秒  
spring.datasource.minEvictableIdleTimeMillis=300000
# 校验SQL，Oracle配置 spring.datasource.validationQuery=SELECT 1 FROM DUAL，如果不配validationQuery项，则下面三项配置无用  
spring.datasource.validationQuery=SELECT 'x'
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
# 打开PSCache，并且指定每个连接上PSCache的大小  
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
# 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙  
spring.datasource.filters=stat,wall,log4j
# 通过connectProperties属性来打开mergeSql功能；慢SQL记录  
spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
# 合并多个DruidDataSource的监控数据  
spring.datasource.useGlobalDataSourceStat=true

5.配置druid-bean.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd">

    <!-- 配置_Druid和Spring关联监控配置 -->
    <bean id="druid-stat-interceptor"
        class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor"></bean>

    <!-- 方法名正则匹配拦截配置 -->
    <bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut"
        scope="prototype">
        <property name="patterns">
            <list>
            
            		<!-- 也就是修改这个地方的文件路径，其他的不用动-->
                <value>com.mypack.mapper.*</value>

            </list>
        </property>
    </bean>

    <aop:config proxy-target-class="true">
        <aop:advisor advice-ref="druid-stat-interceptor"
            pointcut-ref="druid-stat-pointcut" />
    </aop:config>

</beans>

6.Application主类的配置

package com.mypack;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ImportResource;

@SpringBootApplication
@ComponentScan("com.mypack")  
@MapperScan("mapper")
@ServletComponentScan  //主要注解，添加这个
@ImportResource(locations = { "classpath:druid-bean.xml" })  //主要注解，添加这个
public class SpringbootDruid01Application {

	public static void main(String[] args) {
		SpringApplication.run(SpringbootDruid01Application.class, args);
	}

}

Student实体类的创建

package com.mypack.entity;

public class Student {
	int id;
	String name;
	int age;
	String address;

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

	public String getAddress() {
		return address;
	}

	public void setAddress(String address) {
		this.address = address;
	}

}

Dao层的建立

StudentMapper.java

package com.mypack.dao;

import java.util.List;

import org.apache.ibatis.annotations.Mapper;

import com.mypack.entity.Student;

@Mapper
public interface StudentMapper {
	
public List<Student> queryAllStu();

	
}

StudentMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
 
 
 <mapper namespace="com.mypack.dao.StudentMapper">
 
 	<!-- 查询所有学生 -->
 	<select id="queryAllStu" resultType="Student">
 		select * from stu
 	</select>

 </mapper>

service层
StudentServiceImpl

package com.mypack.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.mypack.dao.StudentMapper;
import com.mypack.entity.Student;

@Transactional
@Service
@ComponentScan("com.mypack.dao")
public class StudentServiceImpl implements StudentServiceIF {

	
	@Autowired
	StudentMapper studentMapper;
	
	//查询所有学生
	@Override
	public List<Student> queryAllStu(){
		return studentMapper.queryAllStu();
	}
}

StudentServiceIF

package com.mypack.service;

import java.util.List;

import com.mypack.entity.Student;

public interface StudentServiceIF {

	//查询所有学生
	List<Student> queryAllStu();

}

controller层

package com.mypack.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.mypack.entity.Student;
import com.mypack.service.StudentServiceIF;

@Controller
@RequestMapping("/student")
public class StudentController {

	@Autowired
	StudentServiceIF studentService;

	// 查询所有学生
	@RequestMapping("/listall")
	public String queryAllStu(Model model) {
		List<Student> stuList = studentService.queryAllStu();
		model.addAttribute("stu", stuList);
		return "index";
	}

}

Druid的Config

1.DruidConfigration

package com.mypack.config;

import java.sql.SQLException;

import javax.sql.DataSource;

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;

@Configuration  
public class DruidConfigration {  
    @Value("${spring.datasource.url}")

    private String connectionProperties;  
    @Value("${spring.datasource.useGlobalDataSourceStat}")  
    private boolean useGlobalDataSourceStat;  
  
    @Bean     //声明其为Bean实例  
    @Primary  //在同样的DataSource中，首先使用被标注的DataSource  
    public DataSource dataSource(){  
        DruidDataSource datasource = new DruidDataSource();  
        datasource.setUrl(this.dbUrl);  
        datasource.setUsername(username);  
        datasource.setPassword(password);  
        datasource.setDriverClassName(driverClassName);  
  
        //configuration  
        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.setMaxPoolPreparedStatementPerConnectionSize(maxPoolPreparedStatementPerConnectionSize);  
        datasource.setUseGlobalDataSourceStat(useGlobalDataSourceStat);  
        try {  
            datasource.setFilters(filters);  
        } catch (SQLException e) {  
            System.err.println("druid configuration initialization filter: "+ e);  
        }  
        datasource.setConnectionProperties(connectionProperties);  
        return datasource;  
    }  
}

2.DruidFilter

package com.mypack.config;

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 DruidFilter extends WebStatFilter {

}

3.DruidServlet

package com.mypack.config;

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="192.168.16.110,127.0.0.1"),// 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="admin"),// 密码
            @WebInitParam(name="resetEnable",value="false")// 禁用HTML页面上的“Reset All”功能
    })
public class DruidServlet extends StatViewServlet {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

}

7.index页面测试

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
	主页面
	<table>
		<tr>
			<td>编号</td><td>姓名</td><td>年龄</td><td>地址</td>
		</tr>
		<tr th:each="stu : ${stu}">
			<td th:text="${stu.id}"></td><td th:text="${stu.name}"></td>
			<td th:text="${stu.age}"></td><td th:text="${stu.address}"></td>
		</tr>
	</table>
</body>
</html>

8.看效果

查询效果

登陆到Druid后台

用户名密码就是admin 后台DruidServlet中设置的

ze

这个就是刚才第一次查询的记录

嗯，感觉还不难哈，都是一些配置
源码放在码云了配置源码
