Liferay Service Builder抛出三个奇怪的错误

（老问题）

我正在对Liferay进行一些测试。为此，我正在关注MVC教程，并陷入了服务的困境。

我为测试目的创建了一个简单的实体，“Miclase”：

public class Miclase {
    int num1;
    String string1;
}

很简单，呵呵。好吧，在此之后，我启动了服务构建器并使用Overview窗格创建了这样的文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 6.2.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_6_2_0.dtd">
<service-builder package-path="asd">
    <author>hp</author>
    <namespace>Miservicio</namespace>

    <entity name="Miclase" local-service="true">
        <column name="num1" type="int" primary="false"></column>
        <column name="string1" type="String"></column>


        <!-- PK fields -->

        <column name="miclaseId" type="long" primary="true"></column>

        <!-- Group instance -->

        <column name="groupId" type="long"></column>

        <!-- Audit fields -->

        <column name="companyId" type="long"></column>
        <column name="userId" type="long"></column>
        <column name="userName" type="String"></column>
        <column name="createDate" type="Date"></column>
        <column name="modifiedDate" type="Date"></column>
        <finder name="GroupId" return-type="Collection">
            <finder-column name="groupId"></finder-column>
        </finder>
    </entity>
</service-builder>

在“概述”窗格中显示所有内容都没有错误，所以我点击了“构建服务”按钮，它创建了很多源代码：

但是...在上一次输出之后，我得到以下构建失败：

我在这里做错了吗？

1 个答案:

答案 0 :(得分：0)

我犯了同样的错误，我已经解决了6个小时！

解决方案很简单：

您需要转到Window - Preferences - Server - Runtime Environments，选择您的环境，按edit，然后选择JDK 1.7.0_79，但不 1.8.x.。不同版本存在问题。

我希望它可以节省很多时间。 ：d
