这篇文篇将介绍,如何通过SpringBoot整合Druid数据库链接池,实时监控数据库链接信息,为优化数据库性能提供更好的指导,同样将通过YML配置文件形式进行配置,方便简洁。
环境:
windows
jdk 8
maven 3.0
IDEA

注意:这里引入了lombok
插件节省编写实体类时候写get
和set
方法,这里在idea
中进行set
和get
操作需要下载lombok
插件,在设置页面的plugins
中搜索lombok
插件在中央插件库下载后重启idea
即可,更详细的lombok使用教程可以查考:

这里进行了mybatis
整合,如果不会mybatis
整合可以参考我写的这篇文章:
SpringBoot非官方教程 | 第六篇:SpringBoot整合mybatis
在工程resources
文件夹下新建文件夹log
,并在该文件夹下创建logback.xml
文件,加入以下配置:

name
的属性值一定要是当前工程的java
代码的完整目录,因为mybatis
打印的日志级别是debug
级别的,因此需要配置debug
级别日志扫描的目录。
在工程java
代码目录下创建config
的目录在下面创建DruidDBConfig
类加入以下代码:
@Configuration
public class DruidDBConfig {
@Bean
public ServletRegistrationBean druidServlet() {
ServletRegistrationBean reg = new ServletRegistrationBean();
reg.setServlet(new StatViewServlet());
reg.addUrlMappings("/druid/*");
//设置控制台管理用户
reg.addInitParameter("loginUsername","root");
reg.addInitParameter("loginPassword","root");
// 禁用HTML页面上的“Reset All”功能
reg.addInitParameter("resetEnable","false");
//reg.addInitParameter("allow", "127.0.0.1"); //白名单
return reg;
}
@Bean
public FilterRegistrationBean filterRegistrationBean() {
//创建过滤器
FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
filterRegistrationBean.setFilter(new WebStatFilter());
Map<String, String> initParams = new HashMap<String, String>();
//忽略过滤的形式
initParams.put("exclusions", "*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*");
filterRegistrationBean.setInitParameters(initParams);
//设置过滤器过滤路径
filterRegistrationBean.addUrlPatterns("/*");
return filterRegistrationBean;
}
}
**注意:**这里ServletRegistrationBean
配置bean中通过addInitParameter
设置了管控台的用户名密码都是root
,可以在这里进行自定义配置也可以将这里的用户名密码通过转移数据库进行定制化配置实现。
在工程java
代码目录下创建entity
的目录在下面创建Student
类加入以下代码:
@Data
@EqualsAndHashCode(callSuper = false)
public class Student {
private static final long serialVersionUID = 1L;
/**
* 主键id
*/
private Integer sno;
/**
* 学生姓名
*/
private String sname;
/**
* 性别
*/
private String sex;
/**
* 生日
*/
private String birth;
/**
* 年龄
*/
private String age;
/**
* 简介
*/
private String dept;
}
在工程java
代码目录下创建controller
的目录在下面创建StudentConteroller
类加入以下代码:
@Controller
@RequestMapping("/student")
public class StudentConteroller {
private static final Logger LOGGER = LoggerFactory.getLogger(StudentConteroller.class);
@Autowired
protected StudentService studentService;
/**
* 查询所有的学生信息
*
* @param sname
* @param age
* @param modelMap
* @return
*/
@ResponseBody
@GetMapping("/list")
public String list(String sname, Integer age, ModelMap modelMap) {
String json = null;
try {
List<Student> studentList = studentService.getStudentList(sname, age);
modelMap.put("ren_code", "0");
modelMap.put("ren_msg", "查询成功");
modelMap.put("studentList", studentList);
json = JSON.toJSONString(modelMap);
} catch (Exception e) {
e.printStackTrace();
modelMap.put("ren_code", "0");
modelMap.put("ren_msg", "查询失败===>" + e);
LOGGER.error("查询失败===>" + e);
json = JSON.toJSONString(modelMap);
}
return json;
}
}
在工程java
代码目录下面创建service
目录在下面创建StudentService
类加入以下代码:
public interface StudentService {
/**
* 查询所有的学生信息
*
* @param sname
* @param age
* @return
*/
List<Student> getStudentList(String sname, Integer age);
}
在工程java
代码目录下的service
的目录下面创建impl
目录在下面创建StudentServiceImpl
类加入以下代码:
@Service("StudentService")
@Transactional(readOnly = true, rollbackFor = Exception.class)
public class StudentServiceImpl implements StudentService {
@Autowired
StudentDao studentDao;
@Override
public List<Student> getStudentList(String sname, Integer age) {
return studentDao.getStudentList(sname,age);
}
}
在工程java
代码目录下创建dao
的目录在下面创建StudentDao
类加入以下代码:
public interface StudentDao {
List<Student> getStudentList(@Param("sname")String sname, @Param("age")Integer age);
}
在工程resource
目录下创建mapper
的目录在下面创建StudentMapper.xml
映射文件加入以下代码:
<mapper namespace="cn.zhangbox.springboot.dao.StudentDao" >
<select id="getStudentList" resultType="cn.zhangbox.springboot.entity.Student">
SELECT
s.sno,
s.sname,
s.sex,
s.dept,
s.birth,
s.age
FROM
student s
WHERE
1 = 1
<if test="sname != null">
and s.sname = #{sname}
if>
<if test="age != null">
and s.age = #{age}
if>
select>
mapper>
@SpringBootApplication
@MapperScan("cn.zhangbox.springboot.dao")//配置mybatis接口包扫描
public class SpringBootDruidApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(SpringBootDruidApplication.class, args);
}
}
