日志几乎是一个项目的第二最重要的东西，而繁多的日志框架、各种依赖版本冲突 ，真的是头都疼。
一般项目满足以下条件就差不多了
- 基本日志输出, 能打成可执行jar包
- 日志的持久化, 入文件
SpringBoot+Mybatis+Druid+log4j 日志打包
- 把
SpringBoot自带的日志功能关闭
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<exclusions>
<!-- 切换log4j2日志读取 -->
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
- 添加
Mybatis依赖
<!-- log-file config start -->
<!-- 配置 log4j2 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>
<!-- 识别 log4j2.yml文件 -->

<!-- log-file config end -->
- 添加

SpringBoot方式打可执行jar包
<build>
<finalName>video_black_incs</finalName>
<plugins>
<!-- 打 数据源+日志 的可执行依赖包 -->
<!-- 什么 shade、assembly 都是垃圾 -->
<!-- 楼上+1 -->
<!-- 楼上+1 -->

- 数据源监控
- 过滤器
import com.alibaba.druid.support.http.WebStatFilter;
import javax.servlet.annotation.WebFilter;
import javax.servlet.annotation.WebInitParam;
@WebFilter(
urlPatterns = "/",
initParams = {
@WebInitParam(name = "exclusions", value = "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*")
}
)
public class DruidStatFilter extends WebStatFilter {
}
- 监控器
import com.alibaba.druid.support.http.StatViewServlet;
import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;
@WebServlet(
urlPatterns = {"/druid/*"},
initParams = {
@WebInitParam(name = "loginUsername", value = "admin"),
@WebInitParam(name = "loginPassword", value = "test"),
@WebInitParam(name = "resetEnable", value = "false")
}
)
public class DruidStatViewServlet extends StatViewServlet {
}
访问(账密上面配置)
