New Maven dependcy打开jOOQ日志记录

Question

最近我添加了新的依赖项目来生成.xls文件.

的pom.xml

    <dependency>
      <groupId>org.jxls</groupId>
      <artifactId>jxls</artifactId>
      <version>2.0.0</version>
    </dependency>
    <dependency>
      <groupId>org.jxls</groupId>
      <artifactId>jxls-poi</artifactId>
      <version>1.0.0</version>
    </dependency>

码

 public StreamingOutput createStreamedExcelReport(Map<String, Object> params, String templateName, String[] columnsToHide) throws Exception {
        try(InputStream is = ReportGenerator.class.getResourceAsStream(templateName)) {
            assert is != null;
            final Transformer transformer = PoiTransformer.createTransformer(is);
            AreaBuilder areaBuilder = new XlsCommentAreaBuilder(transformer);
            List<Area> xlsAreaList = areaBuilder.build();
            Area xlsArea = xlsAreaList.get(0);
            Context context = new PoiContext();
            for(Map.Entry<String, Object> entry : params.entrySet()) {
                context.putVar(entry.getKey(), entry.getValue());
            }
            xlsArea.applyAt(new CellRef("Sheet1!A1"), context);
            xlsArea.processFormulas();
            return new StreamingOutput() {
                @Override
                public void write(OutputStream out) throws IOException {
                    ((PoiTransformer) transformer).getWorkbook().write(out);
                }
            };
        }
    }

不幸的是,它可能会打开jOOQ调试日志记录,这非常糟糕,因为它会记录所有数据库查询.应用程序正在对.xls进行大查询,因此它不应该记录(在3分钟内输出~1,5GB).

通过日志配置彻底修复

默认情况下,jOOQ通过它首先在类路径上发现的这三个日志框架中的任何一个使用调试日志记录:slf4j,log4j , java.util.logging. jxls库依赖于slf4j的logback,如pom.xml中所示:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.12</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jcl-over-slf4j</artifactId>
    <version>1.7.12</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>1.1.3</version>
</dependency>

为了关闭jOOQ调试日志记录,您应该相应地配置日志框架(在这种情况下:logback).

在jOOQ中快速修复:

您还可以通过指定以下内容直接关闭jOOQ中的大多数日志记录:

Settings.withExecuteLogging(false);
