struts2 注解配置

1、web.xml

<!-- struts2 配置 -->
	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>
			org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
		</filter-class>
		<init-param>
			<param-name>actionPackages</param-name>
			<param-value>com.yz.webapp.action</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping> 

struts.properties

#修改时重新加载
struts.configuration.xml.reload = true
#打印更多错误信息
struts.devMode = true
#注解扫描的包结尾名
struts.convention.package.locators = action
#映射扩展名
struts.action.extension = html
#结果资源所在路径
#struts.convention.result.path = /WEB-INF/pages

2、action 类名上加注解

@Namespace("/ssi")
@ParentPackage("json-default")
@Action(value = "admin", results = {
		@Result(name = "success", location = "/WEB-INF/pages/admin.jsp"),
		@Result(name = "json", type = "json", params = { "excludeProperties","adminMgr" }) })
public class AdminAction extends BaseAction{}

多个Action

@Namespace("/msa")
@Result(name = "json", type = "json", params = { "excludeProperties",
    ".*Manager,.*\\.authorities,.*\\.roles,.*\\.fileCon" })
@Actions(value = {
    @Action(value = "foreignship", results = { @Result(name = "success", location = "foreignship/foreignship.jsp") }),
    @Action(value = "foreignshipsee", results = { @Result(name = "success", location = "foreignship/foreignshipsee.jsp") }) })
public class TMsaForeignShipArchivesAction extends BaseAction{}

在类方法上加注解

 //@Action(value = "add", results = { @Result(name = "success", location = "/index.jsp") })
 @Action(value = "save")
	public String save() {
		try{
			adminMgr.insert("insertYz_admin", admin);
		}catch(Exception e){
			msg = e.toString();
			success = false;
		}
		return  this.SUCCESS;
	}
