springboot打包war部署到weblogic，涉及Filter以及Filter中的@Value处理

基于Maven构建。

1：修改pom.xml配置文件

<packaging>warpackaging>

<dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-webartifactId>

            
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.bootgroupId>
                    <artifactId>spring-boot-starter-tomcatartifactId>
                exclusion>
            exclusions>
        dependency>

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-tomcatartifactId>
            <scope>providedscope>
        dependency>

2：修改Application

@ServletComponentScan
@SpringBootApplication
public class XtqmServerApplication  extends SpringBootServletInitializer implements WebApplicationInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(XtqmServerApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(XtqmServerApplication.class, args);
    }

}

3：Filter

@Component
@WebFilter(filterName = "xtqmFilter", urlPatterns = {"/xtqm/*"})
public class XtqmFilter implements Filter {
    @Override
    public void init(FilterConfig filterConfig){}

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

    }

    @Override
    public void destroy(){}

}

（1）必须覆写init与destroy方法，否则部署到weblogic中会报抽象方法异常错误；

（2）在Filter中不能直接使用@Value获取配置文件中的变量信息，通过静态工具类的方式实现：

@Component
public class SecretProperty {

    private static String secres;

    public static String getSecres() {
        return secres;
    }

    @Value("${jk.secret}")
    public void setSecres(String secres) {
        this.secres = secres;
    }
}

4：weblogic.xml

                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
