java - 使用 Java 的 MyBatis 生成器无法正常工作

Question

MyBatis 生成器不想为我生成代码。我为此使用 Eclipse IDE。起初我怀疑 targetProject 属性，但我为其指定了当前文件夹，实际上也没有结果。

我可以从命令行使用相同的 xml conf 来正常工作。

我认为我必须以某种方式在我的Java代码中提供outputFolder，我尝试了prop.setProperty("generated.source.dir", System.getProperty("user. dir")); 但它不起作用。

因此，任何建议都将不胜感激。

这是我的生成java代码

public class GeneratorMyBatis {

    public static void main(String args[]) {
        try {
            generate();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static void generate() throws Exception {
        System.out.println("Working Directory = " + System.getProperty("user.dir"));
        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        File configFile = new File("src//main//resources//mybatis//generator//config//generatorConfig.xml");
        Properties prop = new Properties();
        prop.setProperty("generated.source.dir", System.getProperty("user.dir"));
        ConfigurationParser cp = new ConfigurationParser(prop, warnings);
        Configuration config = cp.parseConfiguration(configFile);
        config.validate();
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        ProgressCallback progress = new VerboseProgressCallback();
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(progress);
    }
}

我的配置 xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

        </javaModelGenerator>

        <sqlMapGenerator targetPackage="xml"  targetProject="\">

            <generatedKey column="id" sqlStatement="MySql" identity="true" />
        </table>
    </context>
</generatorConfiguration>

总而言之，我找到了解决问题的方法。

MyBatis 生成所有必需的人员，但将其放入磁盘根目录，例如 D:\。

要在 java targetProject 和 targetPackage 上进行配置，您必须将它们设置到 Configuration 对象中。像这样的事情:

Configuration config = cp.parseConfiguration(configFile);
config.getContexts().get(0).getJavaModelGeneratorConfiguration().setTargetProject(TARGET_PROJECT_PATH);
config.getContexts().get(0).getJavaModelGeneratorConfiguration().setTargetPackage(MODEL_TARGET_PACKAGE);
config.getContexts().get(0).getSqlMapGeneratorConfiguration().setTargetProject(TARGET_PROJECT_PATH);
config.getContexts().get(0).getSqlMapGeneratorConfiguration().setTargetPackage(XML_MAPPER_TARGET_PACKAGE);
