Question

我想在我的实现中使用日志记录。我已将log4j.properties设置为登录控制台和文件：

# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, CONSOLE, FILE

# CONSOLE is set to be a ConsoleAppender.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender

# CONSOLE uses PatternLayout.
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

# Define the file appender
log4j.appender.FILE=org.apache.log4j.FileAppender

# Set the name of the file
log4j.appender.FILE.File=${catalina.home}/logs/smartcv.log

# Set the immediate flush to true (default)
log4j.appender.FILE.ImmediateFlush=true

# Set the threshold to debug mode
log4j.appender.FILE.Threshold=debug

# Set the append to false, overwrite
log4j.appender.FILE.Append=false

# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

这是我的主要应用程序类：

import org.apache.log4j.Logger;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@ComponentScan
@EnableAutoConfiguration
@SpringBootApplication
public class SmartcvfrontApplication {
    final static Logger logger = Logger.getLogger(SmartcvfrontApplication.class);

    public static void main(String[] args) {
        logger.debug("Debug log message");
        logger.info("Info log message");
        logger.error("Error log message");
        SpringApplication.run(SmartcvfrontApplication.class, args);
    }
}

现在，在我的项目的哪个文件夹中放置属性，甚至完全删除它都没关系 - 日志会显示在我的控制台中，但是没有创建文件。
这个以及我可以完全删除属性的事实使我怀疑Spring Boot只是忽略了属性文件而只是使用基本配置。

有谁看到我在哪里出错？

更新：我按照了答案，现在文件在我的C盘上，而我认为它将在我的项目中。这应该发生还是我出错了？此外，当我想从我的ThermostatController等其他类登录时，它不会将其添加到日志文件中......我在这里做错了什么？
这是ThermostatController类的一部分：

@Controller
public class ThermostatController {
    final static Logger logger = Logger.getLogger(ThermostatController.class);

    // Temperatures
    private static int currentTemperature;
    private static int chosenTemperature;

    @GetMapping("/")
    public String loadThermostatView(Model model) {
        logger.info("Load ThermostatView");
        model.addAttribute("currentTemperature", getcurrentTemp());
        model.addAttribute("chosenTemperature", getchosenTemperature());
        return "thermostatView";
    }
}

编辑：这是我的pom.xml，只是为了澄清。

我遇到了同样的问题，以下解决方案没有帮助我 ......

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j</artifactId>
    <version>1.3.8.RELEASE</version>
</dependency>

...所以我尝试用下一个替换它

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
        <exclusions>
            <exclusion>
                <groupId>ch.qos.logback</groupId>
                <artifactId>logback-classic</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>log4j-over-slf4j</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    ...
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.25</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.7.25</version>
    </dependency>

它有效！ ......如果问题仍然存在 - 试试吧！也许这种方式可以帮到你。

您的配置似乎是正确的。如果您已将属性文件放在正确的路径中，那么您的依赖项可能有问题。然后用以下内容替换您的依赖项并尝试：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j</artifactId>
    <version>1.3.8.RELEASE</version>
</dependency>

Spring（Boot）忽略我的log4j.properties文件
