使用idea新建springboot项目beetl-spring-boot-starter 首先添加pom依赖
packaging要设置为jar不能设置为pom<packaging>jar</packaging>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><scope>provided</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId><optional>true</optional></dependency><dependency><groupId>com.ibeetl</groupId><artifactId>beetl</artifactId><version>3.0.0.M1</version></dependency>
编写BeetlProperties
@Component @ConfigurationProperties(prefix = "beetl") public class BeetlProperties {/*** 是否开启beetl 默认开启*/private Boolean enabled = true;/*** 模板根目录 默认templates*/private String templatesPath = "templates";/*** 注册的beetl全局共享变量*/private Map<String,Object> vars = new HashMap<>();/*** beetl自定义全局函数*/private Map<String,Class> FNP = new HashMap<>();public Boolean isEnabled() {return enabled;}public void setEnabled(Boolean enabled) {this.enabled = enabled;}public String getTemplatesPath() {return templatesPath;}public void setTemplatesPath(String templatesPath) {this.templatesPath = templatesPath;}public Map<String, Object> getVars() {return vars;}public void setVars(Map<String, Object> vars) {this.vars = vars;}public Map<String, Class> getFNP() {return FNP;}public void setFNP(Map<String, Class> FNP) {this.FNP = FNP;}}
编写 BeetlAutoConfiguration （使用ConditionalOnProperty注解确定是否加载beetl beetl.enabled=false 的话就不加载beetl了）
@Configuration @ConditionalOnProperty(name = {"beetl.enabled"},havingValue = "true",matchIfMissing = true) @EnableConfigurationProperties({BeetlProperties.class}) public class BeetlAutoConfiguration {@Autowiredprivate BeetlProperties beetlProperties;@Bean(name = "beetlConfig")@ConditionalOnMissingBean(name={"beetlConfig"})public BeetlGroupUtilConfiguration beetlGroupUtilConfiguration(){BeetlGroupUtilConfiguration beetlConfig = new BeetlGroupUtilConfiguration();ClassLoader loader = Thread.currentThread().getContextClassLoader();if(loader==null){loader = BeetlAutoConfiguration.class.getClassLoader();}//beetlConfig.setConfigProperties(extProperties);//额外的配置，可以覆盖默认配置，一般不需要ClasspathResourceLoader cploder = new ClasspathResourceLoader(loader, beetlProperties.getTemplatesPath());beetlConfig.setResourceLoader(cploder);beetlConfig.init();//如果使用了优化编译器，涉及到字节码操作，需要添加ClassLoader beetlConfig.getGroupTemplate().setClassLoader(loader);//注册全局变量 beetlConfig.getGroupTemplate().setSharedVars(beetlProperties.getVars());//注册全局函数for(Map.Entry<String,Class> map:beetlProperties.getFNP().entrySet()){beetlConfig.getGroupTemplate().registerFunctionPackage(map.getKey(),map.getValue());}return beetlConfig;}@Bean(name = "beetlViewResolver")public BeetlSpringViewResolver beetlSpringViewResolver(@Qualifier("beetlConfig") BeetlGroupUtilConfiguration beetlConfig){BeetlSpringViewResolver beetlSpringViewResolver = new BeetlSpringViewResolver();beetlSpringViewResolver.setContentType("text/html;charset=UTF-8");beetlSpringViewResolver.setOrder(0);beetlSpringViewResolver.setConfig(beetlConfig);return beetlSpringViewResolver;}// @Bean(name = "beetlViewResolver") // @ConditionalOnMissingBean(name = {"beetlViewResolver"}) // public BeetlSpringViewResolver beetlSpringViewResolver(){ // BeetlSpringViewResolver beetlSpringViewResolver = new BeetlSpringViewResolver(); // beetlSpringViewResolver.setContentType("text/html;charset=UTF-8"); // beetlSpringViewResolver.setOrder(0); // beetlSpringViewResolver.setConfig(beetlGroupUtilConfiguration()); // return beetlSpringViewResolver; // } }
然后在resources 下面新建 META-INF/spring.factories
org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.chao.beetl.BeetlAutoConfiguration
在其他项目引入就可以使用了
