我有2个模式A,B.我在B中重用了一些A元素.

我不使用命名空间.

我正在使用

<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.9.0</version>

我已经在模式B中定义了模式A的包含:

<xs:include schemaLocation="classpath:my.schema.A.xsd"/>

和目录为

REWRITE_SYSTEM "classpath:my.schema.A.xsd" "maven:my.schema:schema-a!/A.xsd"

jaxb配置如下:

<configuration>
    <generatePackage>my.schema.b</generatePackage>
    <schemaIncludes>
        <includes>B.xsd</includes>
    </schemaIncludes>
    <episodes>
        <episode>
            <groupId>my.schema</groupId>
            <artifactId>schema-a</artifactId>
        </episode>
    </episodes>
    <catalog>src/main/catalog/catalog.cat</catalog>
</configuration>

问题在于,每当我指定episode依赖项时,架构都不会生成任何类,即使它包含一些我希望为其生成类的B元素.

[INFO] Parsing input schema(s)...
[INFO] Compiling input schema(s)...
[INFO] Cleaning package directories.
[INFO] Finished execution.

当我删除这一集时,它运作良好,并为模式A生成类 - 我确实想避免.

你有什么建议吗？

一个样本发表在Jaxb情节汇编中

这是一个非常简单的DAO尝试,我想分享.

我的问题是,这是否是测试DAO的正确方法.我的意思是我正在验证SQL查询并给它返回一个模拟.然后告诉mock返回这些特定值并断言它们？

我已经更新了DAO以使用预处理语句而不是简单的Statement.谢谢.

public class PanelDao implements IO {

    private final static Logger LOGGER = Logger.getLogger(PanelDao.class);

    private Connection connection;

    public PanelDao() throws SQLException {
        this(MonetConnector.getConnection()); 
    }

    public PanelDao(Connection connection) throws SQLException {
        this.connection = connection;
    }

    @Override
    public void save(Panel panel) throws SQLException {
        final String query = "INSERT INTO panels VALUES ( ?, ?, ?, ?, ?, ?, ? )";
        final PreparedStatement statement = connection.prepareStatement(query);
        statement.setString(1, panel.getId());
        statement.setString(2, panel.getColor());
        statement.setDate(3, (new Date(panel.getPurchased().getTime())) );
        statement.setDouble(4, panel.getCost());
        statement.setDouble(5, panel.getSellingPrice()); …

如果可以实现它,你能看看我的连接池吗？

public class ConnectionPool {
    private static List<DBConnection> pool = null;
    private static int available = 0;
    private ConnectionPool() {}

    public static DBConnection getConnection() {
        if (pool == null) {
             pool = new ArrayList<DBConnection>();
             for (int i = 0; i < 3; i++) {
                 try {
                    pool.add(new DBConnection());
                    available++;
                } catch (SQLException e) {
                    e.printStackTrace();
                }
             }
        }
        if (pool.size() > 0) {
            available--;
            return pool.remove(available);
        } else {
            return null;
        }
    }

    public static void returnConnection(DBConnection c) {
        pool.add(c); …

这个问题是比较Java中包含的日期.

有没有更好的方法来检查给定日期是否包含在一个范围内？

Date startDate, endDate, dateToCheck;

if ( dateToCheck.equals(startDate) || 
     dateToCheck.equals(endDate) || 
    (dateToCheck.after(startDate) && dateToCheck.before(endDate) )
