springboot lombok slf4j logback集成

集成Spring Boot、Lombok、SLF4J和Logback有以下几个步骤：

1. 引入依赖：在`pom.xml`文件中引入以下依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<!-- Lombok依赖 -->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <optional>true</optional>
</dependency>

<!-- SLF4J依赖 -->
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.25</version>
</dependency>

<!-- Logback依赖 -->
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
</dependency>

2. 创建日志配置文件：在`src/main/resources`目录下创建`logback.xml`文件，并在其中配置日志输出格式、日志级别等信息。示例配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

    <!-- 定义日志输出格式 -->
    <property name="LOG_PATTERN" value="%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n"/>

    <!-- 控制台输出 -->
    <appender name="consoleAppender" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>${LOG_PATTERN}</pattern>
        </encoder>
    </appender>

    <!-- 文件输出 -->
    <appender name="fileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>logs/spring-boot-demo.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>logs/spring-boot-demo-%d{yyyy-MM-dd}.log</fileNamePattern>
        </rollingPolicy>
        <encoder>
            <pattern>${LOG_PATTERN}</pattern>
        </encoder>
    </appender>

    <!-- 定义日志级别 -->
    <root level="INFO">
        <appender-ref ref="consoleAppender"/>
        <appender-ref ref="fileAppender"/>
    </root>

</configuration>

3. 在代码中使用SLF4J：使用SLF4J的API进行日志输出，示例代码如下：

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

    private static final Logger LOGGER = LoggerFactory.getLogger(HelloController.class);

    @GetMapping("/hello")
    public String hello() {
        LOGGER.debug("debug message");
        LOGGER.info("info message");
        LOGGER.warn("warn message");
        LOGGER.error("error message");
        return "Hello, world!";
    }

}

4. 使用Lombok简化代码：使用Lombok注解简化代码，示例代码如下：

import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@Slf4j
public class HelloController {

    @GetMapping("/hello")
    public String hello() {
        log.debug("debug message");
        log.info("info message");
        log.warn("warn message");
        log.error("error message");
        return "Hello, world!";
    }

}

以上就是集成Spring Boot、Lombok、SLF4J和Logback的步骤。
