    public void create() throws SQLException{
        Statement sta = dataSource.getConnection().createStatement();
        try {
            sta.executeUpdate("CREATE TABLE orders ( id INT NOT NULL PRIMARY KEY AUTO_INCREMENT, item VARCHAR(50), amount INT, description VARCHAR(300), processed BOOLEAN, consumed BOOLEAN);");
        } catch (SQLException e) {
            LOGGER.info("Table orders already exists");
        }
    }

    public void destroy() throws SQLException {
        dataSource.getConnection().close();

推荐答案

您必须使用以下代码设置数据库

You have to setting up your database using following code

<!-- this is the JDBC data source which uses an in-memory only Apache Derby database -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="org.apache.derby.jdbc.EmbeddedDriver"/>
<property name="url" value="jdbc:derby:memory:orders;create=true"/>
<property name="username" value=""/>
<property name="password" value=""/>
</bean>

<!-- bean which creates/destroys the database table for this example -->
<bean id="initDatabase" class="org.apache.camel.example.sql.DatabaseBean"
  init-method="create" destroy-method="destroy">
<property name="dataSource" ref="dataSource"/>
</bean>

<!-- configure the Camel SQL component to use the JDBC data source -->
<bean id="sql" class="org.apache.camel.component.sql.SqlComponent">
<property name="dataSource" ref="dataSource"/>
</bean>
