Dependency injection discourages object-oriented programming? @ Blog of Adam Warski - 0 views

  • Dependency injection discourages object-oriented programming?
  • if you’re using DI, and you have an X entity, do you have an XService or XManager with lots of method where X is the first argument?

    • kuni katsuya
       
      well, dependency injection, but moreover, the soa approach to service design tends to force otherwise intelligent software engineers into doing procedural design the services just end up being bags of method calls that implement any type of behavior, with the domain objects or entity beans being reduced to mere data structures with little responsibility or behavior beyond persistence. (which, in this anti-pattern, is typically mostly provided by the repository or dao class! ie. domain object crud)
  • it’s just easier
    • kuni katsuya
       
      ... if you just blindly follow the anti-pattern, of course  ;)
  • many benefits
    • kuni katsuya
       
      with the procedural approach, you also cannot implement polymorphic behavior, for instance
  • builder
  • fluent interface
  • it’s not for small projects
    • kuni katsuya
       
      fuckwhat? small or big matters not. if di is applied poorly, regardless of project size, it's an anti-pattern! disregard these comments!

Unquiet Code | Using Generics To Build Fluent API's In Java - 0 views

  • Using Generics To Build Fluent API's In Java
  • extends BaseClass
  • super(ChildClass.class)
  • ...19 more annotations...
  • accomplish the same idea using generics
  • creates a bad sort of dependency where we need to update the base class every time we make a new derived class. Not good!

  • The type parameter is saying “the Child class must extend Base<Child>”, forcing the Child class to provide its own type to the type system
  • Now that we can return the derived class in our chained method calls we are free to alternately call methods from the base class and the derived class

Stephen Colebourne's blog: Javadoc coding standards - 0 views

  • Javadoc coding standards
  • explain some of the rationale for some of my choices
  • this is more about the formatting of Javadoc, than the content of Javadoc
  • ...63 more annotations...
  • Each of the guidelines below consists of a short description of the rule and an explanation
  • Write Javadoc to be read as source code
  • Making Javadoc readable as source code
  • Public and protected
  • All public and protected methods should be fully defined with Javadoc
  • Package and private methods do not have to be, but may
  • benefit from it.
    • kuni katsuya
       
      think of it as internal design documentation when you revisit this code 8 months from now: - based on nothing but your well-chosen ;) package/class/method/variable names, will you recall all of your current design intentions and rationale? likely not - when you hand-off this code to another software engineer, how easy will it be to mostly rtfm? will you have to waste time preparing design/implementation notes specifically for the hand-off? if this is the case because the code is unreadable and not self-guiding and there's not already at least high level design notes in a wiki, you're doing it wrong!
  • If a method is overridden in a subclass, Javadoc should only be present if it says something distinct to the original definition of the method
    • kuni katsuya
       
      ie. don't just copy-paste the javadoc from the superclass. that's mindless and pointless monkey work
  • Use the standard style for the Javadoc comment
  • Do not use '**/' at the end of the Javadoc
  • Use simple HTML tags, not valid XHTML
  • XHTML adds many extra tags that make the Javadoc harder to read as source code
  • Use a single <p> tag between paragraphs
  • Place a single <p> tag on the blank line between paragraphs:
    • kuni katsuya
       
      this at least makes the paragraph breaks wysiwygísh and somewhat easier to read
  • Use a single <li> tag for items in a list
  • place a single <li> tag at the start of the line and no closing tag
  • Define a punchy first sentence
  • it has the responsibility of summing up the method or class to readers scanning the class or package
  • the first sentence should be
  • clear and punchy, and generally short
  • use the third person form at the start
  • Avoid the second person form, such as "Get the foo"
  • Use "this" to refer to an instance of the class
  • When referring to an instance of the class being documented, use "this" to reference it.
  • Aim for short single line sentences
  • Wherever possible, make Javadoc sentences fit on a single line
  • favouring between 80 and 120 characters
  • Use @link and @code wisely
  • @link feature creates a visible hyperlink in generated Javadoc to the target
  • @code feature provides a section of fixed-width font, ideal for references to methods and class names
  • Only use @link on the first reference to a specific class or method
  • Use @code for subsequent references.
  • This avoids excessive hyperlinks cluttering up the Javadoc
  • Never use @link in the first sentence
  • Always use @code in the first sentence if necessary
  • Adding a hyperlink in that first sentence makes the higher level documentation more confusing
  • Do not use @code for null, true or false
  • Adding @code for every occurrence is a burden to both the reader and writer of the Javadoc and adds no real value.
  • Use @param, @return and @throws
  • @param entries should be specified in the same order as the parameters
  • @return should be after the @param entries
  • followed by @throws.
  • Use @param for generics
  • correct approach is an @param tag with the parameter name of <T> where T is the type parameter name.
  • Use one blank line before @param
  • This aids readability in source code.
  • Treat @param and @return as a phrase
  • They should start with a lower case letter, typically using the word "the". They should not end with a dot. This aids readability in source code and when generated.
  • treated as phrases rather than complete sentences
  • Treat @throws as an if clause
  • phrase describing the condition
  • Define null-handling for all parameters and return types
    • kuni katsuya
       
      ideally, if the method in question has any specified/required pre and/or post conditions, they should be noted in the javadoc, not *just* null handling also, there are cleaner ways to design around this type of old school null handling hackage
  • methods should define their null-tolerance in the @param or @return
  • standard forms expressing this
  • "not null"
  • "may be null"
  • "null treated as xxx"
    • kuni katsuya
       
      DO NOT DO THIS this is just bad design
  • "null returns xxx"
    • kuni katsuya
       
      this might also stink of poor design ymmv
  • In general the behaviour of the passed in null should be defined
  • Specifications require implementation notes
  • Avoid @author
  • source control system is in a much better position to record authors
  • This wastes everyone's time and decreases the overall value of the documentation. When you have nothing useful to say, say nothing!
    • kuni katsuya
       
      likewise with javadoc on things like default constructors /**  * Creates an instance of SomeClass  */ public SomeClass() {} is equally useless and unnecessarily clutters up the source code

Data Source Configuration in AS 7 | JBoss AS 7 | JBoss Community - 0 views

  • Data Source Configuration in AS 7
  • Using @DataSourceDefinition to configure a DataSource
  • This annotation requires that a data source implementation class (generally from a JDBC driver JAR) be present on the class path (either by including it in your application, or deploying it as a top-level JAR and referring to it via MANIFEST.MF's Class-Path attribute) and be named explicitly.
  • ...21 more annotations...
  • this annotation bypasses the management layer and as such it is recommended only for development and testing purposes
  • Defining a Managed DataSource
  • Installing a JDBC driver as a deployment
  • Installing the JDBC Driver
  • deployment or as a core module
  • managed by the application server (and thus take advantage of the management and connection pooling facilities it provides), you must perform two tasks.  First, you must make the JDBC driver available to the application server; then you can configure the data source itself.  Once you have performed these tasks you can use the data source via standard JNDI injection.
  • recommended way to install a JDBC driver into the application server is to simply deploy it as a regular JAR deployment.  The reason for this is that when you run your application server in domain mode, deployments are automatically propagated to all servers to which the deployment applies; thus distribution of the driver JAR is one less thing for administrators to worry about.
  • Note on MySQL driver and JDBC Type 4 compliance: while the MySQL driver (at least up to 5.1.18) is designed to be a Type 4 driver, its jdbcCompliant() method always return false. The reason is that the driver does not pass SQL 92 full compliance tests, says MySQL. Thus, you will need to install the MySQL JDBC driver as a module (see below).
  • Installing a JDBC driver as a module
  • <module xmlns="urn:jboss:module:1.0" name="com.mysql">  <resources>    <resource-root path="mysql-connector-java-5.1.15.jar"/>  </resources>  <dependencies>    <module name="javax.api"/>  </dependencies></module>
  • jboss-7.0.0.<release>/modules/com/mysql/main
  • define your module with a module.xml file, and the actual jar file that contains your database driver
  • content of the module.xml file
  • Under the root directory of the application server, is a directory called modules
  • module name, which in this example is com.mysql
  • where the implementation is, which is the resource-root tag with the path element
  • define any dependencies you might have.  In this case, as the case with all JDBC data sources, we would be dependent on the Java JDBC API's, which in this case in defined in another module called javax.api, which you can find under modules/javax/api/main as you would expect.
  • Defining the DataSource itself
  •    <datasource jndi-name="java:jboss/datasources/MySqlDS" pool-name="MySqlDS">      <connection-url>jdbc:mysql://localhost:3306/EJB3</connection-url>         <driver>com.mysql</driver>
  •     <drivers>      <driver name="com.mysql" module="com.mysql">        <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>      </driver>    </drivers>

Permission (Apache Shiro 1.2.1 API) - 0 views

  • A Permission represents the ability to perform an action or access a resource. A Permission is the most granular, or atomic, unit in a system's security policy and is the cornerstone upon which fine-grained security models are built.
  • a Permission instance only represents functionality or access - it does not grant it
  • permissions are immutable and reflect an application's raw functionality
  • ...4 more annotations...
  • because Permissions represent raw functionality and only change when the application's source code changes, they are immutable at runtime - they represent 'what' the system can do
  • by transitive association, the user 'has' the permissions in their roles
  • all Permission checks are relegated to Realm implementations, and only those implementations really determine how a user 'has' a permission or not
  • Realm could use the semantics described here, or it could utilize some other mechanism entirely

Properties - 0 views

  • Automatic Property Setting
  • Subversion administrators commonly ask if it is possible to configure, on the server side, a set of property definitions which all connecting clients will automatically consider when operating on working copies checked out from that server. Unfortunately, Subversion doesn't offer this feature. Administrators can use hook scripts to validate that the properties added to and modified on files and directories match the administrator's preferred policies, rejecting commits which are non-compliant in this fashion. (See the section called “Implementing Repository Hooks” for more about hook scripts.) But there's no way to automatically dictate those preferences to Subversion clients beforehand.
