1.filter类
加注解：@WebFilter(filterName = "authFilter", urlPatterns = "/*")
代码如下：
package com.activiti.filter;
import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
// renwenqiang
@WebFilter(filterName = "authFilter", urlPatterns = "/*")
public class SystemFilter implements Filter {
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException,
ServletException {
HttpServletRequest request = (HttpServletRequest) servletRequest;
HttpServletResponse response = (HttpServletResponse) servletResponse;
response.setHeader("Access-Control-Allow-Origin","*");
System.out.println(request.getRequestURL());
filterChain.doFilter(request, servletResponse);
}
@Override
public void destroy() {
}
@Override
public void init(FilterConfig arg0) throws ServletException {
}
}2.启动类
加注解：@ServletComponentScan(basePackages = {"com.activiti.filter"})
代码如下：
package com;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.orm.jpa.vendor.HibernateJpaSessionFactoryBean;
import org.springframework.scheduling.annotation.EnableScheduling;
@SpringBootApplication(exclude = {
org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration.class,
org.activiti.spring.boot.SecurityAutoConfiguration.class })
@ServletComponentScan(basePackages = {"com.activiti.filter"})
public class DemoActiviti0108Application {
@Bean
public HibernateJpaSessionFactoryBean sessionFactory() {
return new HibernateJpaSessionFactoryBean();
}
public static void main(String[] args) {
SpringApplication.run(DemoActiviti0108Application.class, args);
}
}3.jquery ajax请求代码实例：

console.log(data);
this.models = data;
