Struts 整合 SpringMVC 过程:这篇文章是我在整合过程中所做的记录和笔记
web.xml :筛选器机制过滤
原机制是拦截了所有 url ,即 <url-pattern>/*</url-pattern>
新机制为了将 structs2 的 url 与 SpringMVC 的 url 区分开来,则修改了拦截属性
<!-- 原代码 --><filter-mapping><filter-name>struts2</filter-name><url-pattern>/*</url-pattern><dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping><!-- 新代码 --><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 配置开始 --><!-- 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.

基于web.xml配置文件的配置属性,需要配置两个Config类:【两个配置的区别】
AppConfig.java
@Configuration @Import({KmAppConfig.class}) public class AppConfig {}
MvcConfig.java
@Configuration @Import({KmMvcConfig.class}) public class MvcConfig {}
-
基于Config类,配置具体的应用Config
KmAppConfig.java
@Configuration @ComponentScan(basePackages = "com.teemlink.km.") //扫描包体 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() {//如何读取配置资源的数据?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控制器基类* @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;}/*** 资源未找到的异常,返回404的状态,且返回错误信息。* @param e* @return*/@ExceptionHandler(RuntimeException.class)@ResponseStatus(HttpStatus.NOT_FOUND)public Resource resourceNotFound(RuntimeException e) {return error(404, "Not Found", null);}/*** 运行时异常,服务器错误,返回500状态,返回服务器错误信息。* @param e* @return*/@ExceptionHandler(RuntimeException.class)@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)public Resource error(RuntimeException e) {return error(500, "Server Error", null);}/*** Restful 接口返回的资源对象* */@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> {/*** 创建实例* @param entity* @return* @throws Exception*/public IEntity create(IEntity entity) throws Exception;/*** 更新实例* @param entity* @return* @throws Exception*/public IEntity update(IEntity entity) throws Exception;/*** 根据主键获取实例* @param pk* @return* @throws Exception*/public IEntity find(String pk) throws Exception;/*** 删除实例* @param pk* @throws Exception*/public void delete(String pk) throws Exception;/*** 批量删除实例* @param pk* @throws Exception*/public void delete(String[] pk) throws Exception;}
-
AbstractBaseService
/*** 抽象的业务基类**/ 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抽象实现,依赖Spring的JdbcTemplate和事务管理支持**/ public abstract class AbstractJdbcBaseDAO {@Autowiredpublic JdbcTemplate jdbcTemplate;protected String tableName;public JdbcTemplate getJdbcTemplate() {return jdbcTemplate;}public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {this.jdbcTemplate = jdbcTemplate;}/*** 构建分页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 ;/*** 获取数据库Schema* @return*/ // protected abstract String getSchema();/*** 获取表名* @return*/protected String getTableName(){return this.tableName;}/*** 获取完整表名* @return*/public String getFullTableName() {return getTableName().toUpperCase();}}
测试框架
-
基本测试框架
/*** 单元测试基类,基于Spring提供bean组件的自动扫描装配和事务支持**/ @RunWith(SpringRunner.class) @ContextConfiguration(classes = KmAppConfig.class) @Transactional public class BaseJunit4SpringRunnerTest {}
-
具体实现:(以Disk为例)
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());} }
