Struts 整合 SpringMVC 過程：這篇文章是我在整合過程中所做的記錄和筆記

web.xml ：篩選器機制過濾

• 原機制是攔截了所有 url ，即 <url-pattern>/*</url-pattern>

• 新機制為了將 structs2 的 url 與 SpringMVC 的 url 區(qū)分開來，則修改了攔截屬性

<!-- 原代碼 --><filter-mapping><filter-name>struts2</filter-name><url-pattern>/*</url-pattern><dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping><!-- 新代碼 --><filter-mapping><filter-name>struts2</filter-name><url-pattern>*.action</url-pattern><dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping><filter-mapping><filter-name>struts2</filter-name><url-pattern>*.jsp</url-pattern><dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping>

web.xml struts 整合 SpringMVC

<!-- SpringMVC 配置開始 --><!-- Configure ContextLoaderListener to use AnnotationConfigWebApplicationContextinstead of the default XmlWebApplicationContext --><context-param><param-name>contextClass</param-name><param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value></context-param><!-- Configuration locations must consist of one or more comma- or space-delimitedfully-qualified @Configuration classes. Fully-qualified packages may also bespecified for component-scanning --><context-param><param-name>contextConfigLocation</param-name><param-value>spring.config.AppConfig</param-value></context-param><!-- Bootstrap the root application context as usual using ContextLoaderListener --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- Declare a Spring MVC DispatcherServlet as usual --><servlet><servlet-name>dispatcher</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- Configure DispatcherServlet to use AnnotationConfigWebApplicationContextinstead of the default XmlWebApplicationContext --><init-param><param-name>contextClass</param-name><param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value></init-param><!-- Again, config locations must consist of one or more comma- or space-delimitedand fully-qualified @Configuration classes --><init-param><param-name>contextConfigLocation</param-name><param-value>spring.config.MvcConfig</param-value></init-param></servlet><!-- map all requests for /km/* to the dispatcher servlet --><servlet-mapping><servlet-name>dispatcher</servlet-name><url-pattern>/km/*</url-pattern></servlet-mapping><!-- SpringMVC 配置結(jié)束 -->

• 基于web.xml配置文件的配置屬性，需要配置兩個Config類：【兩個配置的區(qū)別】

  • AppConfig.java

  @Configuration @Import({KmAppConfig.class}) public class AppConfig {}

  • MvcConfig.java

  @Configuration @Import({KmMvcConfig.class}) public class MvcConfig {}

• 基于Config類，配置具體的應(yīng)用Config

  • KmAppConfig.java

  @Configuration @ComponentScan(basePackages = "com.teemlink.km.") //掃描包體 public class KmAppConfig implements TransactionManagementConfigurer,ApplicationContextAware { private static ApplicationContext applicationContext;@Autowired private DataSource dataSource; @Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {KmAppConfig.applicationContext = applicationContext; } public static ApplicationContext getApplicationContext() {return applicationContext; }@Bean public DataSource dataSource() {//如何讀取配置資源的數(shù)據(jù)?String url = "jdbc:jtds:sqlserver://192.168.80.47:1433/nj_km_dev";String username = "sa";String password = "teemlink";DriverManagerDataSource ds = new DriverManagerDataSource(url, username, password);ds.setDriverClassName("net.sourceforge.jtds.jdbc.Driver");return ds; }@Bean public JdbcTemplate jdbcTemplate(DataSource dataSource){return new JdbcTemplate(dataSource);} @Override public PlatformTransactionManager annotationDrivenTransactionManager() {return new DataSourceTransactionManager(dataSource); } }

  • KmMvcConfig.java

  @Configuration @EnableWebMvc @ComponentScan(basePackages = "com.teemlink.km.**.controller") public class KmMvcConfig extends WebMvcConfigurerAdapter {@Overridepublic void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {configurer.enable();} }

基于SpringMVC 的 Controller - Service - Dao 框架

• AbstractBaseController

  /*** 抽象的RESTful控制器基類* @author Happy**/ @RestController public abstract class AbstractBaseController {@Autowired protected HttpServletRequest request;@Autowiredprotected HttpSession session;protected Resource success(String errmsg, Object data) {return new Resource(0, errmsg, data, null);}protected Resource error(int errcode, String errmsg, Collection<Object> errors) {return new Resource(errcode, errmsg, null, errors);}private Resource resourceValue;public Resource getResourceValue() {return resourceValue;}public void setResourceValue(Resource resourceValue) {this.resourceValue = resourceValue;}/*** 資源未找到的異常，返回404的狀態(tài)，且返回錯誤信息。* @param e* @return*/@ExceptionHandler(RuntimeException.class)@ResponseStatus(HttpStatus.NOT_FOUND)public Resource resourceNotFound(RuntimeException e) {return error(404, "Not Found", null);}/*** 運行時異常，服務(wù)器錯誤，返回500狀態(tài)，返回服務(wù)器錯誤信息。* @param e* @return*/@ExceptionHandler(RuntimeException.class)@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)public Resource error(RuntimeException e) {return error(500, "Server Error", null);}/*** Restful 接口返回的資源對象* */@JsonInclude(Include.NON_EMPTY)public class Resource implements Serializable {private static final long serialVersionUID = 2315158311944949185L;private int errcode;private String errmsg;private Object data;private Collection<Object> errors;public Resource() {}public Resource(int errcode, String errmsg, Object data, Collection<Object> errors) {this.errcode = errcode;this.errmsg = errmsg;this.data = data;this.errors = errors;}public int getErrcode() {return errcode;}public void setErrcode(int errcode) {this.errcode = errcode;}public String getErrmsg() {return errmsg;}public void setErrmsg(String errmsg) {this.errmsg = errmsg;}public Object getData() {return data;}public void setData(Object data) {this.data = data;}public Collection<Object> getErrors() {return errors;}public void setErrors(Collection<Object> errors) {this.errors = errors;}} }

• IService

  /**** @param <E>*/ public interface IService<E> {/*** 創(chuàng)建實例* @param entity* @return* @throws Exception*/public IEntity create(IEntity entity) throws Exception;/*** 更新實例* @param entity* @return* @throws Exception*/public IEntity update(IEntity entity) throws Exception;/*** 根據(jù)主鍵獲取實例* @param pk* @return* @throws Exception*/public IEntity find(String pk) throws Exception;/*** 刪除實例* @param pk* @throws Exception*/public void delete(String pk) throws Exception;/*** 批量刪除實例* @param pk* @throws Exception*/public void delete(String[] pk) throws Exception;}

• AbstractBaseService

  /*** 抽象的業(yè)務(wù)基類**/ public abstract class AbstractBaseService {/*** @return the dao*/public abstract IDAO getDao(); @Transactionalpublic IEntity create(IEntity entity) throws Exception {if(StringUtils.isBlank(entity.getId())){entity.setId(UUID.randomUUID().toString());}return getDao().create(entity);}@Transactionalpublic IEntity update(IEntity entity) throws Exception {return getDao().update(entity);}public IEntity find(String pk) throws Exception {return getDao().find(pk);}@Transactionalpublic void delete(String pk) throws Exception {getDao().remove(pk);}@Transactionalpublic void delete(String[] pks) throws Exception {for (int i = 0; i < pks.length; i++) {getDao().remove(pks[i]);}} }

• IDAO

  /****/ public interface IDAO {public IEntity create(IEntity entity) throws Exception;public void remove(String pk) throws Exception;public IEntity update(IEntity entity) throws Exception;public IEntity find(String id) throws Exception;}

• AbstractJdbcBaseDAO

  /*** 基于JDBC方式的DAO抽象實現(xiàn)，依賴Spring的JdbcTemplate和事務(wù)管理支持**/ public abstract class AbstractJdbcBaseDAO {@Autowiredpublic JdbcTemplate jdbcTemplate;protected String tableName;public JdbcTemplate getJdbcTemplate() {return jdbcTemplate;}public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {this.jdbcTemplate = jdbcTemplate;}/*** 構(gòu)建分頁sql* @param sql* @param page* @param lines* @param orderbyFile* @param orderbyMode* @return* @throws SQLException*/protected abstract String buildLimitString(String sql, int page, int lines,String orderbyFile, String orderbyMode) throws SQLException ;/*** 獲取數(shù)據(jù)庫Schema* @return*/ // protected abstract String getSchema();/*** 獲取表名* @return*/protected String getTableName(){return this.tableName;}/*** 獲取完整表名* @return*/public String getFullTableName() {return getTableName().toUpperCase();}}

測試框架

• 基本測試框架

  /*** 單元測試基類，基于Spring提供bean組件的自動掃描裝配和事務(wù)支持**/ @RunWith(SpringRunner.class) @ContextConfiguration(classes = KmAppConfig.class) @Transactional public class BaseJunit4SpringRunnerTest {}

• 具體實現(xiàn)：（以Disk為例）

  public class DiskServiceTest extends BaseJunit4SpringRunnerTest {@AutowiredDiskService service;@Beforepublic void setUp() throws Exception {}@Afterpublic void tearDown() throws Exception {}@Testpublic void testFind() throws Exception{Disk disk = (Disk) service.find("1");Assert.assertNotNull(disk);}@Test@Commitpublic void testCreate() throws Exception{Disk disk = new Disk();disk.setName("abc");disk.setType(1);disk.setOrderNo(0);disk.setOwnerId("123123");service.create(disk);Assert.assertNotNull(disk.getId());} }

創(chuàng)作挑戰(zhàn)賽新人創(chuàng)作獎勵來咯，堅持創(chuàng)作打卡瓜分現(xiàn)金大獎
