    <p>You need the <a href="http://static.springsource.org/spring/docs/3.0.x/javadoc-api/index.html?org/springframework/beans/factory/annotation/Value.html" rel="noreferrer"><code>@Value</code></a> annotation.</p> <blockquote> <p>A common use case is to assign default field values using <code>"#{systemProperties.myProp}"</code> style expressions.</p> </blockquote> <pre><code>public class SimpleMovieLister { private MovieFinder movieFinder; private String defaultLocale; @Autowired public void configure(MovieFinder movieFinder, @Value("#{ systemProperties['user.region'] }"} String defaultLocale) { this.movieFinder = movieFinder; this.defaultLocale = defaultLocale; } // ... } </code></pre> <p><strong>See:</strong> <a href="http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/expressions.html#expressions-beandef-annotation-based" rel="noreferrer">Expression Language > Annotation Configuration</a></p> <hr> <p>To be more clear: in your scenario, you'd wire two classes, <code>MybeanService</code> and <code>MyConstructorClass</code>, something like this:</p> <pre><code>@Component public class MyBeanService implements BeanService{ @Autowired public MybeanService(MyConstructorClass foo){ // do something with foo } } @Component public class MyConstructorClass{ public MyConstructorClass(@Value("#{some expression here}") String value){ // do something with value } } </code></pre> <p>Update: if you need several different instances of <code>MyConstructorClass</code> with different values, you should <a href="http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/beans.html#beans-autowired-annotation-qualifiers" rel="noreferrer">use Qualifier annotations</a></p>

    1. COThanks for the tip, but I don't understand how that relates to setting the constructor arg for the injected bean. From what I can tell from the spring docs, it is good for setting default values, but doesn't specify how to pass a constructor arg.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
