1、在pom文件中引入相關依賴包

</project>

2、配置文件application.yml

mysql和阿里druid配置
spring:
  application:
    name: zytrade-sevice-mobile    #指定應用的名稱建議使用小寫
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    url: jdbc:oracle:thin:@192.168.1.98:1521:orcl
    #url: jdbc:mysql://localhost/test?useSSL=false&serverTimezone=UTC
    username: proOne
    password: proOne123
    #username: root
   #password: 123456
    #driver-class-name: com.mysql.jdbc.Driver
    driver-class-name: oracle.jdbc.driver.OracleDriver
    # 下面為連接池的補充設置，應用到上面所有數據源中
    # 初始化大小，最小，最大
    initialSize: 1
    minIdle: 3
    maxActive: 20
    # 配置獲取連接等待超時的時間
    maxWait: 60000
    # 配置間隔多久才進行一次檢測，檢測需要關閉的空閑連接，單位是毫秒
    timeBetweenEvictionRunsMillis: 60000
    # 配置一個連接在池中最小生存的時間，單位是毫秒
    minEvictableIdleTimeMillis: 30000
    #validationQuery: select 'x'
    testWhileIdle: false
    testOnBorrow: false
    testOnReturn: false
    # 打開PSCache，並且指定每個連接上PSCache的大小
    poolPreparedStatements: true
    maxPoolPreparedStatementPerConnectionSize: 20
    # 配置監控統計攔截的filters，去掉后監控界面sql無法統計，'wall'用於防火牆
    filters: stat,wall,slf4j
    # 通過connectProperties屬性來打開mergeSql功能；慢SQL記錄
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
    # 合並多個DruidDataSource的監控數據
    useGlobalDataSourceStat: true

# mybatis配置
mybatis:
  mapper-locations: classpath*:/zytrade.service.mobile/*.xml

3、啟動類

/**
 * @Author: wu
 * @Description:
 * @Date: Create in 11:19 2017/11/8
 * @Modified By:
 */
@SpringBootApplication
@EnableAutoConfiguration
//@EnableDiscoveryClient
@MapperScan("zytrade.service.mobile.dao")//接口掃描，如果此處不加@MapperScan注解必須在接口類上添加@Mapper注解表明這是一個接口掃描器

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

4、阿里數據池配置類

package zytrade.service.mobile.config;

import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;

@Configuration
public class DruidDataSourceConfiguration {

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource druidDataSource() {
        DruidDataSource druidDataSource = new DruidDataSource();
        return druidDataSource;
    }
//    @Bean
//    public HttpMessageConverters fastJsonHttpMessageConverters(){
//        FastJsonHttpMessageConverter fastConverter=new FastJsonHttpMessageConverter();
//        FastJsonConfig fastJsonConfig=new FastJsonConfig();
//        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
//        fastConverter.setFastJsonConfig(fastJsonConfig);
//        HttpMessageConverter<?> converter = fastConverter;
//        return new HttpMessageConverters(converter);
//    }
    
}

2、

package zytrade.service.mobile.config;
import com.alibaba.druid.support.http.WebStatFilter;
import javax.servlet.annotation.WebFilter;
import javax.servlet.annotation.WebInitParam;

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

}

3

package zytrade.service.mobile.config;
import com.alibaba.druid.support.http.StatViewServlet;
import javax.servlet.annotation.WebServlet;
import javax.servlet.annotation.WebInitParam;
@WebServlet(urlPatterns = "/druid/*", 
    initParams={
            @WebInitParam(name="allow",value="192.168.16.110,127.0.0.1"),// IP白名單 (沒有配置或者為空，則允許所有訪問)
            @WebInitParam(name="deny",value="192.168.16.111"),// IP黑名單 (存在共同時，deny優先於allow)
            @WebInitParam(name="loginUsername",value="admin"),// 用戶名
            @WebInitParam(name="loginPassword",value="123"),// 密碼
            @WebInitParam(name="resetEnable",value="false")// 禁用HTML頁面上的“Reset All”功能
    })
public class DruidStatViewServlet extends StatViewServlet {
    private static final long serialVersionUID = 1L;
    
}

5、項目視圖

 

補充log4j2.xml與 mybatis-conf.xml(mybatis全局配置文件)

1、log4j2.xml

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <properties>
        <!-- 文件輸出格式 -->
        <property name="PATTERN">%d{yyyy-MM-dd HH:mm:ss.SSS} |-%-5level [%thread] %c [%L] -| %msg%n</property>
    </properties>

    <appenders>
        <Console name="Console" target="system_out">
            <PatternLayout pattern="${PATTERN}" />
        </Console>
    </appenders>
    <!--配置mybatis日志 -->
    <loggers>

        <logger name="log4j.logger.org.mybatis" level="debug"
            additivity="false">
            <appender-ref ref="Console" />
        </logger>
        <logger name="log4j.logger.java.sql" level="debug" additivity="false">
            <appender-ref ref="Console" />
        </logger>
        <logger name="com.demo.mapper" level="debug" />
        <root level="info">
            <appenderref ref="Console" />
        </root>
    </loggers>

</configuration>

2、 mybatis-conf.xml

        <!--當沒有為參數提供特定的 JDBC 類型時，為空值指定 JDBC 類型。 某些驅動需要指定列的 JDBC 類型，多數情況直接用一般類型即可，比如

        <setting name="jdbcTypeForNull" value="NULL" />

    </settings>
