springmvc跨域设置

说明

可以使用注解逐个设定，可以可以使用配置全局设定。

CrossOrigin注解

@CrossOrigin(origins = "http://localhost:3000")@RequestMapping(value="/search",method = RequestMethod.GET)@ResponseBody@ApiOperation(value = "查询")public void search(                               @ApiParam(value = "分页,从0开始")                       @RequestParam(required = false,defaultValue = "0") int page,                               @ApiParam(value = "分页大小,默认10")                       @RequestParam(required = false,defaultValue = "10") int size) {    ...}

全局设置

@Configuration
public class ApiAuthConfiguration extends WebMvcConfigurerAdapter {

@Overridepublic void addCorsMappings(CorsRegistry registry) {    super.addCorsMappings(registry);    registry.addMapping("/ ").allowedOrigins("http://localhost:3000");}

}

jquery请求

function search() {
$.ajax({
url: 'http://localhost:8082/api/search',
type: 'GET',
data: {'keyword':'java'},
success: function (res, status) {
if (status == 'success') {
console.log(res.data);
}
},
error: function (data, status) {
if (status == "error") {
console.log(data);
// alert(data);
}
}
});
