The correct answer is getxIndex() setxIndex(int value) if you want them to be used as properties according to section 8.8: Capitalization of inferred names of the JavaBeans API specification (e.g. access them via ${object.xIndex} in a JSP.
Java bean is just a set of conventions. EJB is a standard for J2EE business components. Specifically a Java bean: has a public default constructor; readable property methods precedes with “get”; writable property methods precedes with “set”; and is Serializable. For example, a Java bean with a property of “margin” would minimally look like this: … Read more
Any serializable java class (implementing java.io.Serializable) that follows specific conventions: a no-argument constructor, and properties accessible via get/set/is accessors. The idea is to make it predictable, so that properties etc can be discovered automatically through reflection – of great help in tool and framework development.
I don’t see why an interface can’t define getters and setters. For instance, List.size() is effectively a getter. The interface must define the behaviour rather than the implementation though – it can’t say how you’ll handle the state, but it can insist that you can get it and set it. Collection interfaces are all about … Read more
Java Bean is a normal Java class which has private properties with its public getter and setter method. Java Beans are generally used as helper class. Example – public class User implements java.io.Serializable { private String name; private Integer age; public String getName(){ return this.name; } public void setName(String name){ this.name = name; } public … Read more
A JavaBean is just a plain old Java object that conforms to certain conventions including the use of accessor functions (getFoo/setFoo) for member access, provision of a default constructor and a few other things like that. An Enterprise JavaBean is a component in a Java EE application server which comes in several flavours, the details … Read more
You have a couple of options: Import <import resource=”classpath:config/spring/that-other-xml-conf.xml”/> <bean id=”yourCoolBean” class=”org.jdong.MyCoolBean”> <property name=”anotherBean” ref=”thatOtherBean”/> </bean> Include in the ApplicationContext Construction Make both files a part of your ApplicationContext when you create it => then no import is needed. For example if you need it during testing: @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration({ “classpath:META-INF/conf/spring/this-xml-conf.xml”, “classpath:META-INF/conf/spring/that-other-xml-conf.xml” }) public class CleverMoneyMakingBusinessServiceIntegrationTest … Read more
Yes, Spring can invoke private constructors. If it finds a constructor with the right arguments, regardless of visibility, it will use reflection to set its constructor to be accessible.
As @Korgen mentioned in comments hibernate-validator-5.x.x isn’t compatible with validation-api-1.0.x. This is because of moving to new specification JSR-303 -> JSR-349. There are two ways to solve this issue: 1. Downgrade hibernate validator version (which is implements JSR-303): <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>4.3.1.Final</version> </dependency> 2. If you don’t want to move back from hibernate validator 5 … Read more
JavaBeans: At a basic level, JavaBeans are simply Java classes which adhere to certain coding conventions. Specifically, classes that have public default (no argument) constructors allow access to their properties using accessor (getter and setter) methods implement java.io.Serializable Spring Beans: A Spring bean is basically an object managed by Spring. More specifically, it is an … Read more
