Struts 2 間接實現零配置

所謂間接實現零配置，是指只要做些初始化的配置之後，在以後的開發中基本上不用再對每個Action做配置

struts.xml這樣配置

代碼

<action name="*/*" method="{2}" class="workbench.web.actions.{1}Action">
   <result name="custom">/view/{1}/${target}.jsp</result>
</action>

<script>render_code();</script>

 

struts.properties的配置：

代碼

struts.objectFactory = spring
struts.objectFactory.spring.autoWire = name
struts.devMode = true
struts.enable.DynamicMethodInvocation = false
struts.action.extension =
struts.enable.SlashesInActionNames = true

<script>render_code();</script>

 

然後寫一個BaseAction:

代碼

public abstract class BaseAction {
    protected final String CUSTOM = "custom";
    private String target;
    protected final Log logger = LogFactory.getLog(getClass());
    public String getTarget() {
        return target;
    }
    public void setTarget(String target) {
        this.target = target;
    }

    protected String render(String _target){
        setTarget(_target);
        return CUSTOM;
    }
}

<script>render_code();</script>

 

這樣其餘的Action都可以直接繼承BaseAction，不用再做任何配置
通過return render(target)轉發到指定的jsp頁面,從而間接實現零配置

 

代碼

public class UserAction extends BaseAction{
    private User user;
    private UserService userService;
    public void setUserService(UserService userService) {
        this.userService = userService;
    }

    public User getUser() {
        return user;
    }
    public void setUser(User user) {
        this.user = user;
    }
    public String test(){
        user = userService.get(1l);
        return render("test");
    }
}
