Anypoint Studio FileNotFoundException：无法打开类路径资源[app.properties]，因为它不存在

Question

我在使用Anypoint Studio项目时遇到了问题，它在几天前就已经运行了，但现在却抛出了FileNotFoundException错误。我环顾四周，知道我的文件必须在我项目的资源文件夹中。但它仍然抛出错误，我不知道为什么。有谁能指导我？

我的项目：

我项目的配置XML：

Answer 1

• 尝试classpath:app.properties
• 同时删除并重新导入工作区中的项目

Answer 2

一般情况下，企业级应用程序将在域级别和服务级别具有项目。当我们从存储库中检出域项目，并开始仅构建域项目（使用Maven将域项目作为mule运行）时，它将尝试属性文件和失败。在那种情况下抛出了这个异常。

解决方案：与域一起签出Services项目，并开始构建项目，不会抛出此异常。项目应该成功建立。 确保正确设置JRE和Maven设置并运行mvn clean build。

Answer 3

尝试创建属性占位符

this.sqlite.create({
            name: 'addresses.db',
            location: 'default'
        }).then((db: SQLiteObject) => {
            db.executeSql('INSERT INTO experiences VALUES(?,?,?,?,?)',[name, country, state, city, experience])
            .then(res => {
                console.log('Data Saved into Experiences Table!');
            })
            .catch(e => {
                console.log(e);
            });
        }).catch(e => {
            console.log(e);
        });
