优化这段代码: public FilterRegistrationBean xssFilterRegistration() { FilterRegistrationBean registration = new FilterRegistrationBean(); registration.setDispatcherTypes(DispatcherType.REQUEST); registration.setFilter(new XssFilter()); registration.addUrlPatterns(StringUtils.split(urlPatterns, ",")); registration.setName("xssFilter"); registration.setOrder(FilterRegistrationBean.HIGHEST_PRECEDENCE); Map<String, String> initParameters = new HashMap<>(); initParameters.put("excludes", excludes); registration.setInitParameters(initParameters); return registration; }

可以优化的地方有:
1. 将 `new XssFilter()` 改为使用依赖注入的方式,这样可以更好地管理对象的生命周期,提高代码可维护性;
2. 将 `StringUtils.split(urlPatterns, ",")` 改为直接使用数组,可以避免字符串的处理,提高代码效率;
3. 将 `new HashMap<>()` 改为使用 `Map.of()` 或 `Collections.singletonMap()`,可以减少代码行数,提高可读性。
优化后的代码如下:
```
@Autowired
private XssFilter xssFilter;
public FilterRegistrationBean xssFilterRegistration() {
FilterRegistrationBean registration = new FilterRegistrationBean();
registration.setDispatcherTypes(DispatcherType.REQUEST);
registration.setFilter(xssFilter);
registration.addUrlPatterns(urlPatternsArray);
registration.setName("xssFilter");
registration.setOrder(FilterRegistrationBean.HIGHEST_PRECEDENCE);
registration.setInitParameters(Collections.singletonMap("excludes", excludes));
return registration;
}
```
